its my fav machine at the moment,,, love to no bands, grommets, needle tensioners,,, colour work is simply a breeze,, perfect weight, balance,, look, function,,, I did a piece last night 5 hours on this guys leg just above the ankle, and he said he could sit throw the same again,, hardly felt a thing and I swear this machine could cut tarmac but super efficient at what it does,, just the standard 4.5w motor cant see why ya would need the 10w but I will be defo getting another one of these very soon. for anyone who likes no give, wether dd's or linear,,, guys,,, just get one or try one,,, ya will see what I mean,,,,
