I've had a membership (they charge you for a massage a month, so you use it then or can save them up for later) for about 18 months. Overall, I've been satisfied, though with recent changes to my insurance provider (Sunlife) it has become very difficult to get an appointment with therapists that insurance will cover.
Other than that, the prices are slightly lower than average (with the membership), customer service is fine, therapists know what they're doing and the experience overall is good.
