I have unfortunately called 3 different 800 numbers to get my parents stairlift serviced, only to receive no call-backs, and after speaking with one individual, and calling back the next day to find out why I didn't get a call-back - they told me they had never heard of me, and didn't have any case notes. Nice... Product is generally reliable, but ameriglide service is the worst... don't count on them at all - if you can't repair this product yourself, then you are SOL.
