I have several tools Ryobi 18V but after a few months of use (amateur DIY) both Lithium battery charging and more prenent are unusable. The vacuum table makes a lot of noise and it is very effective, the engine of the circular saw and burned impossible to repair at a reasonable cost or to find one (it is less than 10 but in Japan 30 of shipping, the machine is 60). The ineffective lawn shears it hard rather than cut. Total disappointment on Ryobi products.
