LOSCHEN Metric Open Flex-Head Ratcheting Wrench Combination 12 Pcs/set 8-19mm, Metric Spanner with 72 Teeth, Chrome Vanadium Steel Tubing Ratchet （US and European Patents）

I needed these to help remove a hard to reach power steering hose. And they worked for that. But unfortunately, they were much more difficult to use than I expected because the swivel head is much too loose, and just flops around - so placing the ratchet on the nut and keeping it there is kind of tough - the head is prone to slip off and flop around. This would be much better if there was significantly more friction to move the head, or perhaps if it had several different locking positions. In the end, they did do the job, but I busted a knuckle due to the slipping.

The media could not be loaded.  Well, I do believe that these are some very unique wrenches that will handle some very specific problems. That being said I wish the action was smoother and the flex was a higher quality (with more consistent pressure across the heads swing). I'm not going to send them back, so that says a lot. Lol
