I have a Ryobi one plus cordless drill, angled drill, rotozip, torch and radio, they are great value for money in my opinion. They are getting on a bit now, and the batteries are getting tired. I have given them some proper hammer over the years, and no problems except wear and tear. I think they are way above the DIY stuff, but not in the same league as my Dewalt 18v cordless drill which goes on all day on the same battery. But you get what you pay for. My mate has had his Ryobi kit about as long as me, and he has nearly all the one plus range, he replaced his tired batteries with some new lithium ones and he swears by Ryobi. i think they are a good piece of kit. especially if you want good quality affordable gear to get you on your way. You will need 3 or 4 batteries though, as the circular saw and jigsaw can get through them at a fair old rate.
