I think the 90 days is as fair as it can be. Majority eBay sellers give you 1 Wk. but it takes 14 deays before you receive it. Shipping to Canada is never very fast but Adorama did it in 2. Have been short changed by a few sellers on eBay. So far I bought 4 power winders for my Canons and 1 is excellent and one S L O W. The other 2 did not even make it through 2 rls of 24 shot film. eBay will not do anything after 1 week of the end of sale date. Thank-you for your realistic operations.
