The appeal of Off the Grid is the 24 hour access. I truly like the set-up, a disadvantage though is the single location
They have an excellent staff, I chose to do a one week drop-in, if you're an Arizona Resident you can get a three day pass to check it out. If you have a predictable schedule Off The Grid may be for you. They have Self-powering treadmills, unsure if they are Woodways or not, but definitely an awesome piece of equipment that you rarely see.
Clean towels and bathrooms are always a plus. Pretty much everything you need when training for any endeavor.
The staff is awesome and knew by name, which is a pro and this could bring me back to sign up. I just wish it had multiple locations throughout the Valley as my work schedule is about to be unpredictable.
The Con for me is that I could see myself working out here during their peak hours and there isn't a lot breathing room between the squat rack and the rest of the machines :)
