I have the entire set but after 12 years my 8mm gear started to skip. The rest of them are still going strong! Such a good set for the price. Highly recommend over an expensive snapon, matco, cornwell set

This thing is like a piece of art! Trust me, this will be your most prized wrench. You will be out in the garage late way past your bedtime looking for 10 mm bolts and nuts to try it on. Nicely polished and super fine ratchet teeth make this my favorite box end ratcheting wrench ever. It's everything you've only dreamed of.

If you have a 2004 Honda CRV (4 cyl). You need this tool. To change your drive serpentine belt. It grabs on to the tensioner and allows you to ratchet it from any position the nut is set in. This car has a very tight location with lots and lots of leverage needed to change this belt. with out bending or breaking the tool or slipping or stripping the nut on. or breaking down. A regular serpentine tool will not fit in this location. Expensive tool but it is still cheaper then a shop.

These wrenches are very well built. They are very thin but strong; they can reach into tight spaces. The points are hard and grab onto bolts well.

It worked. It worked like a charm. I was changing out a serpentine belt on my Honda. The way they have the tensioner, you have no way to get a ratchet set in there to get enough lag to put the new belt on. I tried the belt removal tool and tried flat ratcheting wrench but did not work. Regular wrench doesn't have enough angle to really get a good pull on the tensioner with out it popping off the bolt.But this one, this one has a sort of an extention to the wrench where it goes on just right on the tensioner bolt and you can remove and replace belt with ease. I spent half a day trying to use the inadequte tools to put on the serpentine belt. Ordered and bought 2 other type of tools and still ended up failing. Then comes along the Mountain wrench.... Ahhhh, it was great.......... Just the right tool for the job.

I use these at work, they have many applications. Unfortunately they are not lifetime warranty, but they make up for that in price

It's a must have. Very handy high quality piece. It's a beauty and it's not made in China, get it.

A review of a recently purchased tool always has to be taken with a grain of salt because there obviously has not been an opportunity to evaluate durability over time. My only use so far has been for the removal of a stubborn oil pan drain plug. That said, I was pleasantly surprised by the apparent quality of this 13mm x 15mm extra long flex-head wrench. The finish is excellent, and the nicely rounded edges on the shaft make it very comfortable in use. In this regard, it matched up very well against a comparable Snap-On that I used as a benchmark. Unlike some, moreover, the flex heads are not the slightest bit floppy. The wrench is very long, and theoretically a tremendous amount of torque could be applied. With the flex-head design and ratcheting at both ends, however, this is not what the tool is meant for. The real purpose of the extra-long shaft is to facilitate access to hard-to-reach fasteners. Some discretion is called for in using the enormous leverage that this 15 ¾ inch wrench affords, I would think. The ratcheting box ends feature spline drives. Although these are versatile in terms of the many types of fasteners they can turn, I have become less of a fan since I discovered that they will often not fit onto a somewhat rounded bolt head. A standard 12 point, not to mention a 6 point, is better for this purpose. Overall, however, a very decent tool that is nicely finished and seems not to be made to the lowest cost.
