Your review system needs a rethink

I would like to make you aware of a weakness of your review system. For product with 6 month plus warranties people need to be able to give a review after 6 months of use of maybe more. So others can get an idea of how the product lasted over time.Forcing people to give reviews after only 1 week or less of ownership tells us nothing about long term durability(that's just a first impressions review). Allow people to update their reviews on non-perishable goods to give a more accurate discription of ownership. Some who used a product for 2 years has more knowledge about it than some1 who used it for 3 days. Also allow us to ask sellers questions about the applicability of products for certain uses. Like Amazon does.
