Wonderful customer support Wonderful customer support. My treadmill motor started making a loud grinding noise 8 days before the 6 month warranty expired. Sent an email to Sunny. Stephen responded that same day, asking me to send a short vid to verify my problem. Next morning, he replied, and said a new motor was being sent to me! It arrived 3 days later. Excellent company!!!

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.

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

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)!!!

Nice smoith ride and goid fit… I purchased the SF-B12021 exercise bike after listening to several reviews on similar models. I chose this bike after a lengthy conversation with Ursula a customer representative at SF. She sent me additional information and after review I purchased and it was atbmy door steps less than a week later. The bike is smooth ride, study and well made. The many adjustments makes it a good fit for anyone. The assembly was easy but bike is heavy. The packaging was good and secure. All components were available with tools for assembly. My first ride was like wow. For much less than the big box bikes I can still sit my tablet on handle bars and ride in any fitness classes. Thanks again Ursula Tony
