Bought in September 23, was dead by February 24. Would not turn on unless plugged in so we thought it was a dead battery, not unusual for a "renewed" product. I bought a replacement battery and when I went to install I find that the unit was already missing multiple screws from the chassis (had no reason to look before) and from the internals. Installed a new battery and got the same behavior. Unit is now junk. Seems like the 90 guarantee is just long enough to avoid service. Lesson learned, this will be the last amazon renewed item I buy. It wasn't the first and I didn't learn before, I simply chalked it up to the risk you take when you buy refurbished. I've been buying refurb electronics for decades and never had such consistent poor results as I have with Renewed By Amazon.
