I think they are at least comparable to TM and Guarder. I´ve used a PDI 150/ 7mm bearings/ 9,6 V 2000mAh in my version 1 VFC AKSU #73, for a year now. It has a pretty high ROF, and I only just recently replaced the original broken piston. I have opened it for cleaning a few times and all the other parts, gears,motor etc., show no noticeable wear yet. With the new piston and re-shimming it kicks *albatross* like never before.
