I have ordered from MM 3 times over a 2 year period and have always received my order promptly. Their products were delivered as advertised and I must say, having purchased from 3 other online dealers, their packaging was above and beyond. Also all orders are shipped with label “MM Machine Parts”. Their premiums are always 1 of the 2 lowest I have found. If you order tubes or flips, they always put their logo sticker on it but it is easily removed. In summary, great dealer, great prices and great service.
