Well I just did some work with it. Lining at 6.8V with an Ambition 1001RLLT cartridge. This is retouching work on my non-dominant hand thread.Yes I got one a few weeks back ,I haven’t used it yet ,but as you mentioned solid machine for the price , a little trick to Make it quieter and run smoother is a little dab of machine grease or Vaseline on the end of the push rod
So I just did some more work with it, about an hour of retouching work with three carts, 1001RL, a 1205RS and a 1007CM, some lining, some packing and color filling....
All in all I'm surprised at the quality of this "disposable" machine and most certainly won't dispose of it yet. I'm planning on using it more just to see how much it can handle because I now only used a 1001 needle which obviously moves way easier then an 1211M1. I still have some shading work to do, probably with a 1007CM, so I'll report back on that later.
However, at the price you pay for this, an absolute steal...
