The magnet is very strong, no issue there.

I mean the 'bendable' part. The nearest consistency I can think of would be a bag of sand. They are weighty but not rigid. They are not designed to hold their shape. Unfortunately this means that it takes very little sideways force to make them "flop" over.

Still, I can't recommend them highly enough. I use them all the time. Seriously, a PCBite plate with probes on-hand is now a permanent fixture on my main desk. If you do half as much fiddly electronics stuff as I do, they will pay for themselves. But you will also occasionally find them infuriating.
