There is, apparently, a lot of animosity between Dmitry and Cheyenne... but that (and Ttech vs cheyenne) is off topic.

I have an LOD and iCube. I got it a couple of weeks ago. The builder (Dmitry, who also designed the hawk thunder) has so far been a stand up guy, very communicative and he responds quickly to any messages or questions (albeit in German, but thats no problem).

The machine is very nice. Totally minimal. Stainless steel, so it's heavy, but the way it sits in the hand is very comfortable and the weight plays no role really. The machine has adjustable stroke, speed, and give (though even at its hardest setting it still has a fair amount of give) over all the way it hits reminds me a lot of a coil to be honest. The handling of the machine is like drawing with a marker, with no weight off to one side it is perfectly balanced (the cable is also like the hawk cable, so it is super thin and very light). Oh, it is very quiet (but not silent) when it has a cartridge in it, but the plunger inside rattles a little when it isnt set up with a needle (I think it needs the pressure the pushing back against the plunger) I have lined using (Ttech) 5rl and 7rs with no problems. Shaded and packed with 7, 15, and 17 mags also with no problems. Cheyenne cartridges work best with it, but Ttech fit as well. They are a bit tighter, and there is like 1mm of needle hang when the machine is at rest (i have used scissors to trim a tiny bit off of the ttech cartridge plunger and it works fine if the needle hang bothers you)
It is a big change for me to work with the give the machine has, since i have been using only direct drive for quite awhile.
The iCube power supply is super tiny. It is the only power supply that works with the LOD, however the iCube will power any rotary, and is supplied with two sets of cables (one for LOD and one for other rotaries). It has a magnetic base and essentially no other features. Just a little black box.
Right now, the app that works with the systemis not the one Dmitry wrote (that one is still being reviewed by apple) but it works and does everything it needs to. His app made for the iCube has programable presets, and a special feature for using it with the cheyenne hawk thunder so you don't need a start up cable.
There is another similar app for android (similar to the one i am using now) but i have not tried it.
