I got a new TiLite chair and it is one problem after another and vendor is having problems with TiLite refusing to cover them. I've had several TiLite and this chair is a turd. Brand new one of the casters doesn't roll worth the crap without backing the screw out, so I have to really keep an eye on that to make sure it doesn't come out, as it is barely "snug". Not even 1 week with the new chair and the CF camber tube had one of the plugs come out. They got a new one no problem and swapped it out. The compact scissor brakes keeping popping loose, even when sitting still. Now, the replacement camber tube is coming apart. It is a Aero T with titanium ultra light package.because of coding changes, this was the way it was configured instead of just getting a TR3 like I had previously. I had the CF camber tube on my TR3 and never had any separation issues that many had experienced, but my new one sucks. One would think after 4 years they would have fixed the problem? Now, the brakes. Tilite told the vendor they never have issued with them and they were refusing to send new ones under warranty and are blaming me and/or the vendor not being able to adjust them properly. They ARE defective, they don't "lock" properly and there is no positive engagement and the slightest bump will cause them to release. That sure sounds re-assuring they will stand behind their product. After arguing back and forth, the vendor finally got them to send new brakes and when installed, there is a noticeable difference in how they engage. The new ones are almost difficult to release. When the vendor was putting the new brakes on, I showed them the camber tube coming apart, AGAIN. Never have fixed the caster issue, they tried new bearings, but looking at it, the cap is rubbing on the caster itself when tightened down, like the caster itself has a bearing cup that wasn't machined correctly. This isn't my first problems with TiLite customer service,m even before permobil. When I switched from a TR to a TR3, I used the exact same specs, but added an inch to the frame. When it arrived, it was a half inch SHORTER. TiLite said that was within specs. as the CAD shows (+/- 1") in the dimensions? Vendor ate the cost and ordered a new frame with +2 and it ended up only about a half inch longer than my TR with no added frame length and all the other specs being the same. Waiting to hear back about the camber tube(again) and caster?
