I tried class pass under their 1 month trial and I loved it. I have signed up to continue. I was scared to try this at first based on the negative reviews but I am glad I did. During my month trial I tried 6 classes and still had 8 credits left. I tried cycling, aerial hoop, hot yoga, and Barre classes. Most classes were absolutely amazing and some were just ok. Either way I got great workout and was able to try something new. What I love about Class Pass is that I am not stuck at a studio. If one is a dud, I can go try a different class at the studio or go to a completely different studio. I personally don't reserve class more than a 1 hour before they start, unless I know the class is really popular and that I enjoyed it. By doing this, I don't have to worry about cancelling and possibly getting a charge, because I know for sure I am going. Sometimes though it backfires and the class that I looked at earlier is unavailable when I want to book. But that is my fault for waiting. However there are always more classes waiting. Depending on how many cities you select, you may find 5 more classes that are similar, starting at the same time.To address the negative reviews, I really think a lot of the negativity has arisen from people not reading. For example, the one month trial clearly says you will be enrolled in the $79 membership at the end of the trial if you don't cancel or modify. All you need to do is log into your account and change the plan. Class Pass has to start you somewhere in membership, so don't get mad that they choose the midpoint membership, it's your responsibility to change by the deadline. I also read about people being mad about credit prices for classes. If you do the math and look at the studio prices, they are offering classes at a discount price through class pass. I broke it down for one studio. Normally a day pass through them is $20. Through class pass it was $6. While they do want business, they are hoping to get permanent customers, which is why they are offering a deal. They don't want you to go through classpass and always use their studio. Otherwise you will be getting their services for supper cheap. So yes, if you find a studio that you like and you go there multiple times in a month, you may see the credit price rise for their classes. Class credits may also change depending the time the class is offered, how popular it is. You can't blame the studios for wanting to get more money for classes during peak times, they are still offering it at a deal. If you really want to take the class, check the schedule. You will most likely find it at another time or something similar at another studio.People also complain about being charged for missed classes. While I agree this stinks, it does not make class pass shady. Studios can't charge class pass for no shows. It's just like health insurance. A doctor can't charge your insurance if services weren't rendered. That's why you get a bill, which is often more than your copay. Don't be mad at classpass, be mad at yourself. Sometimes things are out of control in your life, but that doesn't mean it needs to cost someone else.
