"Just bought this the other day not used it fully yet. First time I plugged it in the noise was terrible but it seems to have quietened a bit since it was about 100 decibels according to my phone app. I tested it with the biggest gun I have, a masonary t nailer and it worked fine set at 8 bar and this can go upto 10 bar. I fired about 10 nails before it came on to top up. One thing I would say is ignore the screwfix description its not 2hp its 1.5hp and you dont get a hose with it either as they say. Overall it seems a good tool but Ive not really given it a full workout yet."
