Very dangerous tool
Reviewed in the United States on August 19, 2019
I have rarely ever given a tool "one star" before. And the reason I'm giving it one star is not because it's a bad tool. It actually seems like a pretty good tool. But I found it to be extremely dangerous. Anyone who has used pullers in an automotive context (or elsewhere) to remove stuck or corroded parts from each other knows that if the arms of the puller aren't perfectly aligned and clamped evenly and firmly, the puller is bound to fall off when pressure is applied by turning the forcing screw. And sometimes you have to try several or many times until you finally achieve that which you were intending to achieve. Of course safety and caution have to always be exercised in such situations, as the puller could go flying, or could even break if it's pushed past its limits, or if the screw is cocked off center.
This is all par for the course. However, the problem with this tool is, that unlike a regular puller, where the arms are bolted together with the screw, and the whole thing is one assembly, here each arm is basically just inserted into the main piece, and there is nothing holding it in there other than friction; it "clicks" into place when assembling. This is very convenient for the ratcheting design of the puller. However, guess what. If everything isn't aligned perfectly, as I mentioned above, unlike a regular puller where the whole thing kind of just plops to the ground, on this puller the arms can get thrown, with some force, literally twenty feet or more!! Ask me how I know! And after one hit me (painfully) in the leg, I was foolish enough to try it again, and that time it flew twenty feet and hit my car!.
Now I know someone out there is going to comment about the safe and proper use of a puller. That's all very good and nice, but it is impossible to always align things perfectly, and in real world repairs a lot of trial and error is needed.
This seems like a great tool for scenarios where out of alignment concerns don't exist for the arms to the puller body, or where only light and consistent pressure is required to separate two parts, not where the full 5 tons of force is needed. I was even desperate enough after it went flying a few times, to take a plastic kids toy organizer box, and drill a hole in it to put the hex head of the forcing screw through, and to keep the rest of the puller "inside" the box, and used it as a "shield" of sorts, while tightening the screw from outside the hole. Well, that was stupide. The arms flew off and went straight through my shield. Fortunately, I was not hurt. At that point, I decided firmly and positively to stop using it. If I had made a metal shield, I guess it would probably have been ok. I will still keep this tool and use it in tamer and more predictable context. But I think it's important that people be very, very aware of this, as someone could be very hurt, and maybe even killed by improper usage.
Edit: I just want to add one thing after the fact. I know I said this before, but despite the danger, this is a very good puller. I was desperate to get an EXTREMELY stuck axle out of a hub, so after nothing else worked, I went back to this, and used the wheel of the car as a "shield/cage" for protection, and despite falling off four or five times (which would have been quite unsafe without my shield), it did get the axle out, whereas NOTHING else, including other pullers was able to.
