I don't have the Wera Hex-Plus bits, but I do have the Wera Hex-Plus L-keys. Which I'm thinking would be the same thing, but in an L-key instead of a bit. I love them. They really bite into the fastener. The steel used is very high quality, and you can put a lot of torque on them, and they don't bend or break. I've snapped Craftsman Industrial hex bits. But the Wera's take a lot of torque, and hold up well. If the hex-plus bits are as good as the hex-plus L-keys, I'd expected them to also be great. The L-keys have the hex-plus on the one end, and a standard wobble type hex on the other end.
Here's some pics of these:
