I wanted to buy a "good" set of allen bits but the only ones I found were too good for my budget. For my needs - the assembly of Ikeevskaya and similar furniture - this is quite enough. For something more substantial or common, I would suggest moving on to the big brands of kids' tools. They get furniture assembly jobs done much quicker than Bondhus wrenches, or worse, the hex tools that come with the furniture. Just be sure to keep the torque setting low.
