Instruct: Classify Amazon reviews into positive or negative sentiment
Query: BUY AT YOUR OWN RISK

I purchased my Tungsten E Handheld in January and yesterday,March 23,the handheld would not turn on. I tried to work through Palm Customer support since it is covered for 90 days from date of purchase and WHAT A NIGHTMARE. If you speak Indian or Pakistani you may be ok but, it was like talking to a machine with no clue of what you are attempting to describe to them. Everything was like scripted... so... I contacted Amazon and EUREKA!!! in spite of their 30 day return policy, they are sending me a replacement unit. Let's see how long this one will function; after reading some of the other reviews, probably not to long. I bought this based on positive reviews and now it seems I have purchased an expensive piece of junk. DO NOT BUY PALM PRODUCTS BUT, DO TRUST THAT AMAZON WILL TREAT YOU RIGHT.
