Overall, I'd put it somewhere between 3 and 4 stars. Haven't used it a lot yet to judge durability, but overall it appears well made with heavy components. I got this because I have run into situations where I do not want the center ram to turn the way it does with a standard screw-type puller. Instead, it uses a sort of jack handle you pump to advance the ram. By pushing straight forward, the ram will not try to twist anything you are working on, and has much less tendency to try to mushroom the end of the shaft on a hard pull. Overall, it comes neatly packaged in a carrying/storage case, and works pretty well. I like that it can be used as either a 2 jaw or 3 jaw puller, and that you can have the jaws longer or shorter to match the job. The overall design is similar to the old reliable OTC Grip-O-Matic in that as you apply pressure, the jaws tend to hold tighter. It doesn't hold quite as tight as the OTC, but it comes close and is a fraction of the price. Overall I'm glad I got them as they were just what I needed to make a couple jobs go better, and the price was worth the convenience. I consider these to be a 'nice to have' category more than the 'gotta have' category. If I could only have one puller, it would be a Posi-Lock because the jaws are tightened onto the work and held in place with a cage, my 2nd choice would be a convertible OTC Grip-O-Matic internal/external 2 jaw/3 jaw puller, for its versatility and compact size, and when I needed a 3rd style of puller, this one rounded out my collection nicely.
