Ours last more than that and we can prove it since we rent them as well.
Currently, new wheelchairs from China are imported into Singapore. Their prices are about $200, 33% cheaper than our SOMA at $295. But they do not last long.
The brakes will get loose and the wheel will be misaligned after abt 6-8months. Then you would hear squeaky noises from the wheel as they wear out very fast.
These importers do not honor their warranty. We have several clients being charged for the misaligned wheel problem. In the end, they switch to Soma for better quality. Hence low price does not translate to value for money in the long run. So we have to be careful in selecting wheelchairs.
