I made a previous post about being a member at the Tempe location and how I ended up liking this one better, but I just want to clarify.
This location in north Scottsdale and is an onyx club. This means it costs more, but you're clearly getting more. The facility is always kept perfectly clean, the machines are rarely out of commission and the locker room is much bigger and offers more amenities like a steam room, sauna, razors, shaving cream, and other little stuff like that.
I met two of the managers when I went over to switch my membership and they were super nice and friendly. These are all important things to me and make it worth the price.
In the end, find the amenities and little details and overall price you like the most, then make your decision. You can always change to a different level of membership or try it out for a free 3 day pass.
