Does What It Needs Too, Looks Reasonable
I bought the Tuggnut for my SS belt drive, primarily because it was the first tensioner I could find that could be used with a standard quick release skewer. Everything else seems to need a 3/8" bolt-on axle. So far, it has allowed me to get appropriate tension on the belt and looks reasonably good doing it. The quick release hasn't slipped at all, so Surly's recommendation to get just one Tuggnut has been accurate.

The only downsides are that it is about 3 times the price of other tensioners and the blue Loctite on the threads was a pain during the first installation.

PROS: Stylish

CONS: Price

Good but...
Nice chain tensioner. I installed in on my Surly Ogre commuter to set the tire back a cm or so in order to create better clearance/looks with a full rear fender.

You have to use an extra (supplied) washer to make the chain tensioner compatible with a QR skewer. This is the first chain tensioner I've ever had on a bike — and it does exactly what it's supposed to do — but I find it to be kind of a nuisance when putting the wheel on the bike and having to deal with this extra loose/dangling hardware around the skewer. That's more of a symptom of chain tensioners in general than it is a problem with this one though.

PROS: Lightweight, Easy To Install, Durable, Attractive Design

Works great!
I used this to convert an old steel road bike with sliding dropouts to singlespeed. It worked flawlessly and will even open your post-ride beverages.

If I were to give it any criticism i'd say its not the best looking chain tensioner out there, but it makes up for it in utility.

PROS: Versatile, Easy to Use, Durable

Easy to use; practical; reasonable price. Worked with near vertical dropouts to take up just enough slack in chain. Would recommend.

Easy install, does its job perfectly, and can open a bottle much easier than with popping the top of a spoke.

The Tuggnut fits...
The Tuggnut fits nicely onto my Gary Fiasher Triton with Halo Aerorage track wheels. I used to have my rear wheel misalign after a few rides and I have to check my rear wheel and brake before each ride. Now this problem did not happen again and it also makes wheel alignment faster.

Is this a single or a pair?
A shopper on Mar 7, 2017
BEST ANSWER: He product is only a single tuggnut, as you're only "really" supposed to put one on the chain-drive side. That said, I got two and installed one on bob sides. It gives me better peace-of-mind that the bolts will never loosen up one on me ... and allows me to really dial-in the wheel tracking very specifically. Good luck!
