Very quiet and doesn’t shake muchSmaller than expectedGreat product!! Finally used this for the first time last night and was not disappointed.. this machine is a workhorse. I just started tattooing a little over and year ago and have not used many other rotary machines. For me, the Mummy is a game changer. Easy to use, display is clear and easy to see and adjusting voltage is a snap. I would highly recommend this product.I got one of these as a back up machine in case my Cheyenne Hawk Pen dies. I did a couple tattoos with it, and I’m fairly impressed. It hits pretty hard, and it packs great! The only negative for me is that I wish it were a little thinner, but that’s just personal preference. Not too shabby at all.5 day old tattoo really quite no vibration really affordable and easy to clean, definitely bought a second. Produces clean tattoos.Battery lasts but not as long as some say maybe 3-4 hours max so hopefully it stays like that in the long run. Very easy to use and operate.For the price is was awesome?????? great to use???(On ebay without the mummy logo for 85.99) other then the above. the 1 I bought befor Christmas is amazing but I got the new version and had a battery that made a weird buzzing noise when turned off and this is the same if the buzzing noise don't stop in 2 weeks it's going back like the newer version and I'm just gona go buy the unbranded version off ebay for half the price as I don't trust battery's that make noise when there off luckily I have the exact same mummy machine and it's perfect I love these beasts but not if there making weird noises like the battery is going to blow up or something must of had a bad delivery or just have a faulty battery I recommend this if you get 1 that's not making a weird noise it does everything you want it to do but the noise is making me not want to buy this machine off amazon again if I do send this machine back I won't be getting another off here again as I don't trust anything that has a battery and is making noises when it's turned off I would take a video but it can't pick up the noise will try again after I drain the battery and see if that fixes it but I doubt it will.As it is my first one I have to experience to compare. However it holds charge well, no issues after 2 months of use, heavy enough which I consider good. Overall I think it's a good productThe machine worked fine for around a month, though I noticed it would discharge battery very quickly when it was being used. Now after 1 month it has completely stopped charging and is unusable. I've contacted the company for a refund or exchange but haven't heard back.
