I have a 5" angle grinder from Einhell, also cordless, and that's really the only experience I have. This one, although less well known than Einhell, seems to be of excellent quality and seems to work too. It's easy to hold, use and very intuitive. Blades and/or accessories are easy to swap out. Nothing bad to say about that. I would recommend this if the price is right - I've had it for about an hour long used and as it was already out of service and already in use I used it to cut up the pallet to prepare the pallet wood for rubbish collection - and the angle grinder really isn't the best tool for that btw - I knew that and have used it anyway, and while the tool was difficult to hold at that particular angle, I had no problem with its working and the tool stayed loaded the whole time, i used it lossless would recommend - great tool mine came without a case - which is a big downside - but i have a case for it and accessories so it's not a problem.
