Not long ago I bought a 240v ryobi and it wouldn't cut through a bit of 3x2 CLS, initially I thought it may of been the tool itself so took it back and swapped it for a dewalt and the difference was night and day, but now I'm beginning to think it was the blades, I mean how can ryobi get the tool so wrong compared to dewalt when all they both have to do is vibrate which they both seemed to do just fine yet the ryobi just would not penetrate the softwood, purely just from my experience I think I'll steer clear of cheap blades
