Permobil C500 VS Yes or No?

[DogInspired]

I need to get a new Wheelchair. My current chair is a Permobil Street with a Recaro Orthoped seat (leather, heat, cooling, adjustable lumbar and lateral supports, etc.). After living with a C-5 SCI for 22 years, I've just about had my fill of the muscle spasms along with the side effects from the spasm medications, bowel and bladder problems, etc. so I'm really leaning towards making my next chair a Permobil Stander.

I only have two reservations besides missing the outdoor speed, navigation, and comfort of my current chair. The clinician I'm going to be seeing told me he's never really heard anything good about them, in particular he claims people have reported getting pressure sores if the chair is not fitted perfectly and I've read on other forums people claiming that it has a bit too much hardware that hasn't been perfected yet which causes the chairs to constantly need repairs.

I would really appreciate hearing from folks that have been using one. I'd like to know if long-term users are really getting the medical benefits claimed in the studies and if there are really that many people who have had negative experiences with them.

Thanks,
Bob
