The chair I use is the Quickie S-646-SE. The chair has full suspension. The rear suspension has x2 "Fox" spring dampers and the front has a suspension system that is very simular to the "frog legs" that you see on most modern manual wheelchair but much more heavy duty.

I found that the chair had to be driven smoother because of the front suspension. When I first drove it felt very soft in the front and rolled around, if you stopped to quick or turned fast the front frog leg suspension would give you that feeling.

But after a little practice I found I was taking bumps a lot harder and just driving much better because of the soft ride.

The S-646-SE would rate 7.5 out of 10 in my opinion.

Things I like about the S-646-SE:

The chair is very quick.

The suspension is good once you get use to it.

The chair has a great range.

The chair in general drives very well, you feel that the chair drives very true e.g. easier to back-up in long hallways, easier to drive on unlevel ground.

Things I don�t like about the S-646-SE

Footplates are not built strong enough

Wheelbase is a bit shorter which tends to rock you around a little more.

All the fitting are in imperial (nuts, bolts, Ellen keys) because it made in USA.

Not the best to fasten down the rear of the chair in the vehicle. (Fasten points aren�t the best)

The chair was very expensive.

Strengths:Outstanding speed, responsive yet stable handeling with unmatched ride quality from the adjustable suspension. Very good close quarter manuverability. Well thought out battery compartment makes battery maintanence a breeze. Very tough frame and motor combination. I have repeatedly done things that would break my old chair on the spot. Good range once I got the batteries broke in. Great program ability. Turned up I can out manuver my pit bull. Good tilt mechanism. Feels safe and is very durable so far. I tilt back 30 times a day. Nive low seat hieght gets my knees under most tables.

Weaknesses:Out of the box programming was anemic. The chair was hobbled with the factory settings.

The anti-tippers being in constant contact is a drag. They are noisy and hangup on cords and hoses and drags them around. They also flutter at high speed on rough terrain. I wish it would still drive while tilted back. I miss a few phone calls while I get tilted back up to a movable position.

Comments:It needs more tire and wheel options to make it work better off road. I got mine in Mossy Oak camo and I get a ton of positive comments on it. Turned up mine will wheelie for about 40 feet. It's a blast to drive. I have only got it to roll back the power on me twice and I was working the heck out of it. I'm glad it will protect itself because my last chair would just burn itself up without warning. At one year old I just had to change out the front castors and the antitip wheels. I have smoked off 3 sets of drive tires so far.

Strengths:Powerful Motors. Shocks, front and rear.

Weaknesses:Anti tip wheels are designed to constantly keep contact with the ground. There is an easy fix for this though.

Comments:I've had the Quickie 646SE for almost 2 months. Incredable piece of equipment. Very fast when needed. Excelent tork when climbing steep hills. Tight turning radus, even more so than my manual chair. Very stable and easy to control. The ONLY thing I can find that could be better designed is the rear anti-tip wheels are designed to constantly keep contact with the ground. This will drive you nuts when trying to back up onto a curb, use through gravel or any ruff surface. After only a week one of the rear solid anti-tip wheels developed a flat spot which simulated the sound of a flat tire whenever I used the chair making the situation even more frustrating. I have came up with an easy fix that lets me adjust them up to 3 inches off the ground. I adjusted to 1 inch which I found ample for my needs and everything works much better. I've tested the chair with the reclining seat all the way back and it's still very stable. Front wheels do not begin to lift from the ground even with the balanace changed. Overall this is an excelent machine all the way around. I would recomend anyone try it out who is looking for a power chair. I don't think you will look any further.
