In this task, you're given reviews from Amazon's products. Your task is to generate the Summary of the review.

[Q]: Bought two of these. One was pretty nice, but the other made my back hurt; I don't think their quality control on the is very good. Would suggest going with another brand that you are more familiar with
[A]: Bad quality control. Bought 2 chairs: one was good, the other made my back hurt

[Q]: This chair came in a broken taped up box and the seat was missing. Amazon says they can't send the part. Awful
[A]: INCOMPLETE! NO SEAT INCLUDED. AMAZON WON'T SEND ME ONE

[Q]: This review is for Amazon, not for the blades. Do not buy these blades from Amazon unless you know you dont need an adapter swap to install them. For my car, I needed a mini-adapter which didnt come in box with these. Took me a day to figure out what was wrong. Went to Napa and they came with the proper adapter and I got them installed in 30s.
[A]:
Do NOT buy from Amazon unless you know you dont need an adapter for installation
