I've had this walking pad for only 6 weeks. Initially the belt started having no traction, making noise and not going the speed it was registering on the display bar. I adjusted that to no avail. Tuesday I was walking on it at a 5.0 and the belt started slipping again and the motor started emitting a burnt smell and then completely stopped on me in the middle of my face paced walk. I called the CONCETTA number at 909-637-7665 and got some weird voicemail. Shortly afterwards I received a text from that number asking me about what the issue was. I texted that the belt and motor stopped and what had happened. They texted me back and said to "discard" it, and they would send me a replacement. After asking for a tracking number on the replacement, I received no reply. I went onto my walmart account and messaged the company via email. I got a reply telling me to give them the part numbers so they could replace the PARTS. At this point it's already in the garbage container and unsafe to use. I was originally told they would replace the walking pad, only for them to back peddle and want to replace parts. I paid for the extended warranty also. Don't waste your time on extended warranties or with this company. I bought another one with a different company. Not CONCETTA. Terrible customer service and not willing to replace a faulty machine that could have caused serious injury due to the motor and the belt.
