My Obsidian Surge 500 Meter Water… My Obsidian Surge 500 Meter Water Rowing machine sprung a leak while still under warranty after three years of use, and Ursula, Dalia, Kerissa and Minerva of Sunny Health & Fitness helped to provide me with a replacement frame in a very short period of time. Much appreciation to a great staff!

Follow up to December review - they're still rotten. This is a follow-up to my December review. They finally contacted me in mid January, 2 full months after I sent a video/audio highlighting the bike issue. They said they would be sending out replacement parts within 1-4 weeks, and would notify me when the parts shipped. It is now early April...nothing. How does a company that has absolutely NO customer service stay in business??? I guess they must sell enough to unsuspecting people (like me). Like lambs to the slaughter.

Sunny SF-E3911 - good elliptical & great support Sunny SF-E3911 - Support (Carlos) was amazingly helpful!!! I have clocked more than 500 miles on the Sunny SF-E3911 Elliptical machine & love it. Recently, the stepper roller was making thumping noise. Upon examining the rollers - found that one of them was flaking & pitting. Contacted Sunny Support to report the problem & Carlos responded. He agreed the roller needed to be replaced & suggested the other roller as well. As he was processing the replacement order - he said my machine was just outside the warranty period, but will process the order as a one-time replacement. The two rollers arrived about 5 days later & solved the thumping noise problem. Thank you Carlos!!! Now I can go another 500 miles (or more)!!!

Easy to assemble, great to use I'm 5 feet tall, 65 and female but put my step trainer together easily and quickly by myself! I broke both my ankles and one fibular a year ago and needed a smooth exerciser to strengthen my ankles and for cardio exercise. The stepper is just the thing and shows all the details you need throughout your workout. I highly recommend this exerciser

Carlos Carlos, great help in assisting me with recumbent bike issue and seller on Amazon. I’m still perplexed that the model I received was actually a different model than was ordered once the casing was removed. Can’t get belt back on but I can “free-style peddle” with zero tension. Bummer but Carlos tried his best to help and was very pleasant.
