Very good price / quality ratio, with very good performance for a device like this. Warning: it is imperative to a lithium battery preferably 4 Ah, otherwise you will be disappointed! And the battery (approx. 100 without charger) is more expensive than the grinder itself! With a good battery the device provides. This grinder is robust design. Excellent for extra work there or you do not have a generator on hand, on the roof, in the garden, but also for work in your workshop or you're fed up son who twists. Cut the stems, make a notch in a corner, etc. For larger locksmith workshop wired grinder remains essential because the "Wireless" is a bit slower (lower rpm), the discs (115 instead of 125) wears out faster, and tends (thermal protection) stalling when attacks of a thin iron. And it takes at least a spare battery louse uninterrupted work. For cutting, consider using cutting discs End (1.6 mm) available from specialist professional providers. I myself am a locksmith, so I speak mainly about performance on iron, I guess on aluminum, copper, PVC, etc. the performance is even better. I already had a grinder Ryobi 18V first generation. I bought it because I already had other tools Ryobi 18V, it makes a battery economy (and the commercial strength of this brand!). First she disappointed me a lot because with Ni / Ca, which work very well for screwdrivers, duration of use was a few minutes. Now with lithium batteries, there is no picture and I use it a lot. This second generation is more powerful and more robust. I recommend. Especially if you already have other tools of this brand in 18V for there amortiriez you high fees batteries faster.
