Easy to use. The felt on the clamps really protects the wood. Great product.

More convenient and faster than using C-Clamps. If one of the stiles refuses to go back flush after tightening up the clamp I use a card board shim only on the side of the stile that needs to be coaxed back flush with the with the other stile. Card board shim strips used for drywall work great.

After years of using hand clamps, I thought I would give these a try. I couldn't believe how much nicer these were to use. The drill guide is used for the pilot hole and then you swing the guide out of the way and finish with the countersink bit. Put the screw in and you on to the next. A depth stop on the countersink bit makes it easy to stop but I did found that a piece of tape works a little easier and it doesn't get in the way of the drill guide. Since I don't do this for a living, the price from Amazon makes this well worth the money. The tool is made to last a more than a lifetime so it would be something that would be passed down or on to someone else.

The Pony cabinet claw clamp is the only clamp that can be used to line up face frame cabinets in two planes. The clamp can be used to clamp two cabinet side face frames together, align them and then provide a drill guide to join them together. The clamps are of good quality and perform well.

These are very helpful when connecting two flush cabinets together, but most kitchens only have a few of such connections. These clamps obviously don't work when attaching a cabinet to a side panel at the end of a cabinet run, or when attaching a cabinet to a 45 degree corner cabinet, etc. The drilling hole in the side is convenient, but doesn't allow you to use a countersink bit because the hole is too small in diameter (at least for the standard countersink bits that I have), so if you want to countersink your face frame screws, which most people do, you have to take off the clamp after drilling your pilot holes, and then re-clamp prior to screwing.

The clamps are high quality construction and work as advertised, but are expensive. If you only have a few cabinets to install, don't spend the money on these. A good pair of quick release clamps and a little extra time is your better option. But if you are a professional installer that does high volume, then I think these are worth it.
