I do a lot of business with them and they always have well cared for gear. I am not an operator and don't have the knowledge to fully test myself. Not saying it won't need adjustments but,it looks like a nice clean unit. Items may need a more in depth cleaning.
Photos are the best. Everything you see in the pictures is what included this lot. Please look at ALL pictures closely before purchasing. I did purchase from a local operator.
