Customer Reviews ProForm 505 CST Treadmill

Are you curious to know what customers are saying about ProForm 505 CST treadmill? Here are a few comments:

The treadmill is quite sturdy and it works okay for the price.” David.C.

It’s just a couple of months old, so I can’t say for sure if it provides value for money. I’m looking forward to seeing if it lives up to my expectations.” Shoxie.

I am really disappointed with this treadmill. I don’t even know why bought it in the first place. It started slowing down on its own and the grumbling noise became even louder to a point of distracting my workouts. I have addressed the issue with the customer support and I’m still waiting for their tech to show up and try to fix the issue.” Thebaldguy.

I bought it three weeks ago and seems to be working just fine. The only issue I have with this machine is the squeaky noise when running on it. It actually gets louder when I increase my speed and it’s quite annoying. I’m sure if I lived in an apartment, I would have pissed off a couple of neighbours.” Doreen Daisy.

Our Verdict on ProForm 505 CST Treadmill

Check More Features on Amazon

Although the ProFormProForm 505 CST does not meet all the performance expectations, its performance will suit you fine for your daily workouts. Plus, the 505 CST has some pretty amazing features and among the best in its price range. Perhaps the most impressive is the 18 built-in workout programs.

This entry-level treadmill, however, lacks certain features that are desirable when exercising. For one, unlike its predecessor, this model is not iFit enabled. Again, the running space is a little bit smaller and this can be an issue for taller people. Of course, you’d expect some shortcomings; given the 505 CST is an entry-level machine. But nonetheless, the 505 CST treadmill offers something for every skill level –whether you’re a beginner, intermediate or fitness fanatic.

So, if you are looking for both reliability and affordability, this treadmill provides you with just that.
