WOW! I mean they meet my needs, maybe some of them. I easily managed to grab a stuck/rusted seatpost bolt on my Peloton bike and twist it in a controlled manner. The extra long handle had a lot of mechanical advantages, allowing me to get a super strong grip and use smaller strokes to apply more pressure. The only thing I have is the handle is at right angles, one jaw moves and the other is stationary. and because of the pivot point of the moveable jaw, it does not maintain a perfect jaw opening. so that the base of the bent hole appears to stick out over the bend on the fixed side. Also, the jaw does not open very wide. Maybe you could grab something 1 inch max if you're lucky. My item was about 3/4 inch (about 17-18mm) and it was perfect for that. Handles are comfortable. The unlocking mechanism works well. Overall I think they are worth it. If they ever fail I will be back to update the review. So far they seem super robust for what they do.
