"My first HPA build cost me $600 in parts and another $150 in labor... The FCU is so easy to use and program, efficient, effective, inexpensive and I mean by hundreds. Customer for life."

"I installed it in my Krytac MK2 and it fit like a glove... the performance was more than what I asked for, and the Catalyst Gen 2 was really easy to tune. I own a Wolverine MTW Gen 3 and I would still recommend the Phoenix to anybody."

"This was a perfect fit in my Krytac Trident MKII PDW-M. I only had to drop the trigger board and engine in place. Not a single issue with alignment. I have put a ton of BBs through it and have had no issues... I just got the same gun for my daughter and plan to add a Phoeni...

"Great budget way to get into HPA. Works flawlessly so far, and air efficiency on basic dwell tuning provides what I estimate about 2-3000 BBs before needing a refill, and that's with the full auto every now and then... Definitely recommended."

"I couldn't be more impressed with the performance of the engine. Once tuned to best efficiency, it keeps up with any other HPA engine on the market. Highly recommended."

"Best engine I've run so far. I thought Polarstar had great customer service from numerous conversations I've had with their techs, but these guys top them, hands down. Plus with the Discord channel, even if they don't answer you quickly, the community will."

"First time going HPA and building it, I had a bit of trouble as a beginner, but paying close attention to the videos and carefully replicating them, I can't really complain. For cost efficiency you can't lie, it's a great intro to HPA!"

"Fast delivery. Well packaged. Easy to set up the engine. The FCU is very easy to use. Very quiet compared to my other Wolverine engines. The rate of fire is awesome. For the price it's unbeatable."
