Kong Compressors?

I've been trying to find out information on these as well. Been talking with Bin from The Pellet Shop and he said he tortured his before starting to sell them and that the little one and the big one have held up well. I may try one in the near future.
Did Bin mention spare parts availability? I have one in my cart at the pellet shop along with the AEA carbine td, but need to reach out before I "buy now"
