This one is wonderful !
It looks as good as you think it should look, feels great and is perfectly made.
hex tip is very well made, it fits into screws very tight (depends on screws of course).
On some screws you have to apply even small force to slide this wrench in and it results in 0 slop.
I have also brand new E-flite driver set and its 1.5 hex is smaller, even there is are screws, where E-flite would turn easy without gripping the screw !
This RDRP wrench take the same screw with slight slop (acceptable to my standards).
I am impressed :)
Design better than any of Hudy wrenches and probably the quality as well - replacement tips are priced fair by my standards.
Anyway if you have 450 heli, you will know that getting good 1.5mm hex is mandatory and this one does everything it is supposed to do !
P.S. you can place this wrench vertically on its flat back, very stable.
Also you can take its back cover off (secured by rubber ring) and place plenty or screws inside to prevent loosing them.
