I have owned 2 Heartway USA products for almost 3 years now, a Vita S12S 4 wheel scooter now approaching 2100 troublefree miles, and a CEO P25 powerchair. I needed a powerchair with a seat elevator as my Muscular Dystrophy has depleated my leg's quad muscles, not enabling me to stand from a seated position.
The S12S scooter has been excellent and enables me to travel places quickly and safely at 11 mph.
The CEO P25 powerchair, although not intended as a rough terrain vehicle has been successfully used as one in my hobby of metal detecting...and I use it a lot for that purpose (in the first 2.5 months of 2016, I logged 117.25 hours of use just during my metal detecting). The 14 x 3" drive tires and 10 x 3 front casters have served me well in areas where the 3" ground clearance won't cause me problems. The elevator system is tough and reliable and is used extensively during my metal detecting escapes. To allow front access for the metal detector, I remove the front leg rests and detect for coins in a half elevated seat position. I rest my feet on top of the front castor mounts. When I locate a target I want to dig, I drop my feet off the castors and lower the seat elevator to its lowest position (19" from ground). This height allows me to use a hand trowel to dig shallow targets (6" depth max.). I am closing in on 1100 coins since the first of this year (2.75 months). With all the trash that I also dig up, and all the other times even at home that I use the seat elevator, I estimate about 10,000+ seat elevator cycles per year. That's a bunch. The seat elevator on this model also allows adequate height to sit at pub table height to watch NFL football at the local establishments.
This chair has only 450W 4-pole drive motors, but the drive system seems more than sufficient to move my 200# carcass around, even in deep grass and semi-rough conditions. The 90 amp R-net control system seems like an adequate match also. Two 75 amp batteries provide me with plenty of hours for semi-rough terrain metal detecting, and all the hours I can stand if detecting in a city or county park.
My Heartway chair and scooter are both made in Taiwan by a dedicated mobility product company. I also own a Pride Quantum 6000Z that costs 3 times what the Heartway CEO P25 did, and the Quantum 6000Z has failed a drive motor, tilt actuator and a few other components during mostly indoor use. I do my own maintainence on my mobility vehicles which on these two Heartway products have only been checks and very little work or adjustments.
