Sunsign ab Crunch Machine Coaster Workout Equipment core Fitness Roller for Home abs Universal Wheel Roller with Knee mat and Total Body Exercise System Coasters Abdominal Trainers, Blue

It will work for it's intended purpose better than what I could make. It is not similar quality or comfort as the actual sn dolly system yet it will still serve its purpose well. It has 2 strategic advantages 1. Its available to be purchased and 2. It is more cost effectiveI would recommend it as a fill in for the other unit or days gyms are closed

This particular ab dolly is of fair quality for the price. However, it's quality was not what I was looking for. I wanted an ab dolly similar to, if not exactly like, the dolly used at a popular fitness studio. I found the item I was looking for so I decided to return the Sunsign product.

I guess you get what you pay for. the wheels on this seem to guide the roller board in a new direction every time you move it. it does not glide freely even if you push it. it just swerves all around due to the cheep wheels. I purchased this to use for ab exercises and it is unusable. maybe some other use would work...i don't know what that would be though. purchased a higher priced piece of equipment from a different company instead.

This is tiny and extremely flimsy. There is no way I could put my weight on it although I am not that heavy.

Llegó ya todo usado y maltratado. Sospecho que era producto devuelto y se entiende completamente, porque el material y el acabado no valen el precio por el que se oferta.

No es fácil de usar y no es lo que esperaba. La calidad del producto es mala.

Excelente producto y calidad

pequeño pero funciona perfecto, muy buena calidad
