Bests & Worsts Reviews from Amazon

I used the travel bottles on two domestic flights, and had carry-on only. When the bottles I used for shampoo and conditioner leaked all over the first time, I thought it was perhaps because I had the bag with liquids packed too tight. I am TSA-pre, and a very frequent traveler. The second time I got "smart" and wrapped the two bottles in a plastic bag before putting them in the bag with liquids. I also very carefully placed the bag with liquids at the very top of my carry-on luggage. For some reason this seemed to be worse. I lost half the bottle of shampoo and the conditioner leaked all over also. I am very surprised by all the positive reviews. It almost makes me wonder if my bottles are defective. I can't even squeeze liquid out of the bottles without the top popping off.
