Outdoor Wheelchair for Recreation
I bought this wheelchair to be used outside to help me get to and from our pool and hot tub. It works great.

Great Service. Good Purchase.
I think that I received the Rollz Electric a day or two after ordering. Great service!
First outing was an overnight at Disneyland. As with all wheelchairs, this chair will take some getting used to. As my husband's caregiver, I use the electric drive-assist function as I push the chair. It definitely makes pushing easier. There is a learning curve. Whenever you take your hand off the chair handles for 5 seconds, you get an error message and have to reset to continue. This could be improved. The back wheels are (naturally) wider than the non-electric Rollz Motion chair, and that takes getting used to maneuvering through doorways and tight spaces. We are having a Surelift 88 installed in the back of our Prius because at around 60 lbs, the Rollz Electric is too heavy for me to lift. Overall, I'm happy with the purchase.

Outstanding product and service by office liaison Jean
The Nano lift arrived in excellent condition. We were impressed with the quality of engineering and manufacturing that went into this product ( I had a metal fabricating shop so I can appreciate quality and precision).My friends, an electrician and carpenter and I installed it in less than a day. I would like to point out that the installation instructions were poor and could use much improvement. We had to refer to the bar code for special videos on many items. Many of these referenced the Hercules lift and not the Nano. My thanks to your office liaison JEAN who did an outstanding job getting us thru the purchase and transport issues we had.THANK YOU JEAN. Yours truly Fred Roesslein
