I was given one (will check brand tomorrow) and the plastic that it relies on for correct angle is crap and never did the right angle. Ozito might be ok but check the build quality.
I have seen some other drill specific sharpeners that I think would be better.

Edit: i used it the first time in a while today, its xu1 not ozito
The xu1 one has holes you drop the drill bits into and a beveled stone tbat runs horizontaly inside.
Its cheap and nasty but mine still cuts a good edge.
Having said that im gental with it but ive done alot of drill bits
