I bought an LED kit from them for my TAF, and it is great, just had one lamp that is ghosting, right lamp just ghosting, so they are sending out a replacement.
Also bought the Blue LED Flipper MOD and my board wasn't like what they had in their directions, so worked with Chris, and he was great, would deal with them again in a heartbeat.
No knife/multi-tool for me, but still a great company (people).
