They are a great all around color/B&G machine. The give won't work properly without the right spring if you are using Carts. The spring it comes with is for needle bars only unless the previous owner ordered the springs from Christian at Inkmachines. If you want to use carts Order the springs from the Inkmachines webcart. also get yourself the toolkit it comes in handy as a lot of those allen screws are not standard sizes. Also if you use Carts besides the give spring, don't forget to remove the up spring.
