2 yrs. ago I purchased the Losi hex and socket wrenches & have had great luck with them. They have a alluminum handle so they have a nice solid feel to them. They are a good quality. I wrench on 3 rc's doing constant maintenance and they have held up with out flaw. I did just recently replace the tip on my 2.0 mm, but it seems to be the 1 that gets used 90% of the time.
