Review: Anjilong (安集龙) AN2601 Pro electronic tension head + electronic brake (ordered from Taobao)
A badminton stringer’s upgrade from a Wise 2086
TL;DR: I swapped the Wise 2086 on my Pro’s Pro Hornet for an AN2601 Pro, a little-known electronic head sold on Taobao, and added the seller’s optional rising diablo and electronic brake upgrade. Total landed cost in Vancouver was CAD $989.54, no duties. That’s less than a new Wise 2086 alone costs in Canada, and the brake gives my manual machine a feature normally found only on machines costing many times more. The head is faster-responding and more rigid than the Wise, and after roughly 20 racquets I’m very happy with it.
Disclosure: I bought this with my own money and have no affiliation with the seller.
Who I am (and the limits of my experience)
I’m a badminton player and I only string badminton racquets, so nothing here speaks to tennis. I lurked the stringing forums for three or four years before buying anything. My brother has a Prince Neos, so I’ve been around machines for a while, and I kept browsing tabletop options that wouldn’t break the bank but would let me string my own racquets on my own schedule instead of paying a shop and waiting to get them back. Along the way I looked at the AEF M9, SIBOASI’s machines, and HUIPAIYIJI’s lineup.
Earlier this summer a friend upgraded to a dedicated Yonex machine and sold me his setup: a Pro’s Pro Hornet with modest upgrades to the clamps and C-mounts, plus a Wise 2086 (Series 13, possibly 14). That would have been perfectly fine to string on for years. I strung on it for a couple of months before the AN2601 Pro arrived in mid-September. Since then I’ve done about 20 racquets on the new setup, stringing as a hobbyist for myself and my wife.
What it is
The AN2601 is an electronic constant-pull tension head built to retrofit existing stringing machines. It comes in standard and Pro versions; the Pro adds a rising diablo. It pulls 10.0 to 80.0 lb in 0.1 lb steps (the increment is adjustable in the settings), weighs 3.8 kg (about 8 lb), runs on 100–240 V at 50/60 Hz, and carries a 2-year warranty.
I haven’t opened mine up, so I can’t speak to the internals. The design and overall shape are close enough to the WISE 2086 that I’d guess it’s based on the same layout, with significantly updated and upgraded components. To be clear though, it’s its own product, not a WISE clone. (photo)
The big one: the electronic brake upgrade
The feature I most want to highlight is the optional electronic brake attachment, and it’s the main reason I’m writing this post.
On cheaper machines, the racquet mount rotates freely. When the tensioner pulls, the mount can shift slightly, and that movement shows up as fluctuation in the tension actually reaching the string. More expensive machines solve this by locking the mount in place while the tensioner is pulling. That’s what this upgrade adds.
It works by replacing the stock racquet mount axle with an electronic brake axle, which then plugs into the tension head. Installation is straightforward: unscrew the mount from the axle, then the axle from the base, then reverse the process with the replacement. That’s it.
In use, the brake can be engaged on its own, or set to trigger automatically when you press the button to start a pull. The activation latency is adjustable to taste, and the brake releases on its own as soon as the tensioner stops pulling.
The seller offers two variants depending on your machine. I messaged him directly on WeChat, and after some back and forth he worked out the right parts for my Hornet. He’s also reachable through Taobao messaging and RedNote (Xiaohongshu/小红书). If you’re considering this, contact him with your machine model and photos before ordering — he’s made adapters for most types of systems and will match the parts to yours.

I paid no duties. The shipping company handled everything. If you ship through Taobao’s own international service, they handle it too, though that route would have cost roughly 50–100% more than the third-party forwarder I used. It’s probably the more trustworthy option if you’d rather not gamble.
Shipment details, in case you’re pricing out air freight yourself: the package declared 8.1 kg (just under 18 lb) at 40 × 40 × 20 cm, covering the head, the brake parts, and all accessories in one box.
Timeline: A couple of days from the seller to the forwarder’s warehouse, then about 9–10 days to fly to Canada, clear customs, and land on my doorstep.
Dealing with the seller: We communicated mainly over WeChat, in Mandarin. If you don’t read Chinese, modern translation tools handle this well enough that I wouldn’t expect it to be a barrier.
Price context: what this actually buys you
A fair comparison for the head itself is the Wise 2086, the standard electronic retrofit in North America (prices as of September 2026):
• RacquetGuys (Canada): CAD $1,099, head only
• Tennishead (US manufacturer): USD $1,101 including US shipping, out of stock at the time with about a 6-week lead time
• Tennis Warehouse (US): USD $799 plus oversize shipping, back-ordered and US-only shipping
• Adapters run USD $79 each and the WISE 2090 calibrator is USD $97. Wise doesn’t offer an electronic brake.
The more interesting comparison is against machines that come with these features built in. I’m not claiming this setup equals them. A Yonex or Wilson comes with a far better mounting system, a stand, and local support. But strictly in terms of electronic tensioning features, here’s roughly what that costs off the shelf:
• Yonex Precision 9.0: CAD $21,000 at Max Sports Canada
• Wilson Baiardo: CAD $9,299 at RacquetGuys; the Baiardo L is CAD $5,999
• Head EX-TE3600: CAD $7,499
• Victor C-7032 Ultra: forum reports put it around CAD $6,500
• Li-Ning E5000: MSRP CAD $6,999.99, discounted to roughly CAD $5,997 at Li-Ning Canada
• Gamma X-LT electronic: CAD $4,299
So a used manual machine plus a roughly CAD $1,000 retrofit puts the tensioning side of things in the same conversation as machines listed at five to twenty times the price. That’s the pitch.
Installation
Relatively easy. All the tools you need are in the package, and Anjilong provides a video to follow if working from a written manual isn’t your thing. I took my time and was extremely careful, so it ran about an hour. If you’re handy and comfortable with tools, it’ll go faster.
One practical note on power: mine shipped with a Chinese Type I cord, but the seller included a universal adapter in the box so I could plug it into a Canadian outlet. The supply is 100–240 V, 50/60 Hz, so no converter is needed.

Baseline for comparison |
A few differences stand out. The AN2601 goes lower on tension (10 lb vs. 15 lb) but tops out lower too (80 lb vs. 86 lb), which is irrelevant for badminton and may matter if you string tennis. It has 6 memory slots instead of 2, which is genuinely useful for saving mains, crosses, and knot tensions across a few frames. On weight the two are near-identical, within about half a pound, so neither is meaningfully more portable.
Stringing experience
Short version: it’s much smoother than the Wise. Five specific differences stand out.
Significantly better gripper and glide-to-activate!
One of the differences between the WISE2086 and more professional stringing machines with their own tension heads is that the gripper and trigger feels a bit outdated and crude. With the Angilon, you not only two buttons to start/stop pulling (one where the trigger is, but also one to the left of the display), you also have glide-to-activate!! It appears to be the same one as the third-party upgrade package that is available for the WISE 2086 on Taobao, but I cannot be certain.
The rising diablo
The Pro version offers a rising diablo instead of a fixed one, and I opted for it. There’s genuine debate over whether this matters, but I think it does. The string gets pulled at an angle closer to level with the racquet, rather than angled slightly downward.
Much faster polling
The tension sensor and its correction loop run noticeably faster than on the 2086. The head responds to micro-fluctuations so quickly that I mostly don’t notice them happening. This is especially apparent because the live tension readout only moves when there’s a meaningful deviation, so the display stays steady where the Wise would show it chasing.
It’s rigid
The Wise 2086 has a floating track, which makes the head feel a bit wobbly, particularly when pulling at an angle. I confirmed this after some back and forth with Dan at Tennishead. The AN2601 is solid by comparison, with no side-to-side play between the puller and the main body.
The 45-second auto-release
Worth knowing before you buy: the Anjilong head automatically disengages after 45 seconds of constant pull. It’s a protective feature to limit wear on the head, and it isn’t adjustable in either direction. It caught me off guard the first time it dropped tension on me, but I got used to it quickly. Forty-five seconds is plenty of time to clamp, so it’s not a deal breaker — just don’t let it surprise you mid-pull.
What I like
• The electronic brake brings a feature normally reserved for far more expensive machines.
• Total cost including the brake and shipping came in under a new Wise 2086 in Canada.
• Faster tension correction and a far more rigid puller than the Wise.
• Six memory slots and a lifetime pull counter are small but welcome touches.
• The seller was responsive and sorted out the right parts for my machine.
What could be better
Honestly, not much. At this price you’re getting a package that punches well above its weight.
The real gap is on the business side rather than the product. There’s no marketing or support presence for this aimed at North America, which is why nobody here has heard of it. If there were, I suspect there’d be a lot of interest. Practically, that means ordering through Taobao and handling support over WeChat rather than walking into a local shop. The warranty is 2 years, and the manufacturer will ship replacement parts for anything that wears out, so in principle there shouldn’t be a failure that a part swap can’t fix.
Who should consider it
DIY-minded stringers who are comfortable ordering from Taobao and messaging the seller, and who want constant pull plus an electronic brake on an existing manual machine for roughly what a Wise 2086 alone costs here. Less suited to anyone who wants warranty service close to home. You should be able to find the seller page by searching "安集龙" on Taobao.
Verdict
For a long time, the North American market has only one option when it comes to upgrading your manual or drop-weight stringing machine with an electronic tension head, and that is the WISE 2086. The Angilon AN2601 Pro is a very, very, attractive alternative (upgrade, even) at roughly the same cost – provided you are comfortable with communicating with the seller overseas.
Happy to answer questions. Just thought to share my thoughts on a discovery that I am excited about.
