From the first time I tried to use it with very little force, it broke in half, very soft; I didn't even manage to do my job once, wasted money.

It does its job, I changed the spark plugs on Opel Astra H. The downside I would say is that its magnet is not strong and you have to remove the spark plug with gentle movements, otherwise the spark plug falls and you have to put the tool back in to catch it again. It needed a stronger magnet. But even so, I got the job done.
