Ergo rounds make their sol nova unlimited much more comfortable and grippy, not to mention how easy wrapping/breaking down the machine is without having to worry about the grip... I wish my flux had disposables 👀
Short version: these grips are trash! Cartridges wiggle a LOT on these grips (yes, I use Cheyenne safety cartridges)
Bought 3 boxes of ergo round to go on my newly purchased sol nova unlimited 4.0 what a let down... they wiggle a lot, and I mean a lot. Cheyenne needs to check the diameters/tolerances on these grips because for equipment this expensive, accessories should have perfect fitment. I contacted Cheyenne, sent them a video illustrating my point and all they said was “we’re sorry” lol. Really? Just for comparison sake, the disposable grips for my packer/shader wands from Bishop hold all brands of cartridges perfectly fine, and they are cheaper than Cheyenne’s.
I tried Kwadron and envy cartridges which are the other 2 brands I use and they also wiggle a lot. In conclusion, stick to you factory grip because these disposable ones are utter trash.
These disposable grips are just what the doctor ordered. I ordered them because the one inch grips were out of stock. But they ended up working great
