Many reviews say the resistance bands fray, snap, or break down after limited use. Numerous customers describe emails going unanswered, refunds taking too long, and orders that were lost or never delivered. Fewer reviewers praise the workout programs and say some equipment holds up well. Ratings show a clear split between people who recommend the products and those who report failures.

Many customers say the products don’t last long, with bands breaking quickly, and call that poor value. Some reviewers say the bands and programs are worth the price. Positive value notes show up less often than durability complaints.
Multiple reviewers report deliveries that never arrived, cancelled orders that still showed up, and refunds that moved slowly. One reviewer points to higher shipping costs when buying equipment. A small number praise the product setup and community resources.
Most reviews describe bands that snap, dry-rot, or wear out after little use. Several reviewers say the bands feel unsafe when they break. A few people say the bands are well made and the home gym equipment is high quality, but those comments appear less often.

Reviews split between people reporting product failures with support that didn’t resolve the issue and those who recommend the programs and equipment.

“Undersun Fitness has one of the best home gym equipment available”
Love this company for multiple reasons:
1. The customer service and support that they provide are simply incredible!
2. I had an issue with my delivery and reached out via email to the company. I was initially frustrated because I read the poor communication reviews and could not find a phone number anywhere. I sent an email on Tuesday and the first thing on Thursday morning, I received a response.
3. The bands alone were a great investment. They have amazing quality and they come with a warranty as well!
5. The programs are excellent!
Overall great experience! I highly recommend Undersun Fitness products and its programs to anyone — regardless of your fitness level.
