9 months with my Kahuna and can say without hesitation this is the best gym equipment purchase I've ever made. The quality of the materials are outstanding, with steel gauges superior to many commercial products. The paint and finishes are German-car-like. The bearings and pulleys are flawless and with normal maintenance (some DW-40 every few weeks) work to perfection.
The accessories are almost too much, and I highly recommend the optional rack which makes storage and space easier. It helps to plan a workout around accessories given that it can take a bit of time to move the many high quality pieces on and off the cage safely, especially if you're alone. This is a rich problem!
The team behind BFN are truly nice guys, Canadian entrepreneurs determined to make the best product anywhere. I don't believe anyone but the handiest of us can build this properly alone, so be sure to take advantage of BFN assembly (tougher for me to get outside GTA, but they did it!)
Some things to think about: The excellent peck deck is commercial grade, but adds significantly to the footprint. I have a large basement, but be mindful of the additional space needed if you don't. I also wish there were more bar stands (there's one, in back and requires high clearance) and I would love a flat/horizontal bar integrated into the great pullup options already standard. Finally, be sure to plan for commercial floor matting, as this machine is to large and heavy to go on most home floors.
In short, this is the ultimate home gym setup, has made a huge difference for my fitness and has been an incredibly reliable workhorse. Daniel and his team have been first rate at every step.
