I've tried both the Wiha and the above Stanley Stubby. Both are good products and broadly equivalent. However, the Stanley has a much stronger magnetic holder, which makes it in practice, in my opinion, for the better Stubby. So I worked with Wiha overhead skylight and on the retreat hung the bit in the screw. Mind you a new screw, neither rusted, filthy still jammed. Then I moved for testing the bit several times by the holder and the force required is minimal. Not so with Stanley, there sits the bit bombproof and can also be released again without any problems. This comes, however, at the expense of size, the Stanley is longer in about half a bit. In my opinion, it is this but worth it, because you should really work on such a narrow room where a half bit length makes the difference, I would be more worried about losing the bit due to the weak magnet and also yes there still wrench that are much flatter and would perhaps more suitable in such situations.
Otherwise, the two stubby same but very. Both are perfectly in the hand and are moved with a non-slip rubber / plastic, which feels not only flexible, but is also a tacky feel. The processing of Stubby and bits also makes a good impression. Weight will vary by content without bits are the stubby lightweight, full magazine again quite heavy. This can be divided according to taste therefore. A slight difference there still in the magazine closures, the Wiha has a buckle, the Stanley turn a screw. The Kunsstoff used is high, so is not likely to wear through ease of use for both. However, since the screw has no protruding parts, I think that this is ultimately more robust.
Decisive for me but was the magnet holder and therefore is my recommendation to the Stanley!
