The first thing a potential purchaser should know is that if you purchase this piece of equipment and you have any problems at all, you will not be able to get in touch with any customer service phone numbers. One rings off the hook, the other goes to a private cell phone. If you contact Walmart Marketplace customer service they will give you the run around for a couple of weeks while they “escalate” the situation multiple times and then you may have the unfortunate experience of dealing with an extremely passive aggressive employee named Celine. After multiple attempts to communicate through email, where I inquired about any insight as to why the cables keep twisting, why are the cables fraying, and why a spacer just popped off. I got a response of please circle the missing parts in the manual. To which I responded, is this an actual person I am talking to because I never said anything about a missing part. We now are the very disappointed owners of an expensive piece of equipment we can not safely use, three months after purchasing. Walmart also admitted they are unable to get in contact with the seller in order to help facilitate any type of resolution. My advice is, before you order any piece of equipment call whatever customer service number they have listed BEFORE purchasing, just in case you have any issues after the fact. If you can’t get in touch with anyone, order somewhere else.
