Q: I bought this from the same co. before christmas and was stunned that the price had doubled. On the page the price was not clear!

Q: I have only wore these boots a couple of times, so I may be reviewing them too soon. As other reviewers have stated they don't seem to need a break in period, but there is a certain "learning" period. I say this as a person who literally has worn nothing but tennis shoes for years. The learning is getting used to the extra weight and bulk on your feet. I bought these to be a part of my "bug out" plan. I will soon be going on a real hike on rougher terrain to see how they feel then. Plus until I have put many more mile on them to see how they hold up I can't say for sure how many stars they deserve. I give them 4 for now and assuming 200-300 miles from now they are still in good shape I would change it to 5.

A: Positive

Q: I bought two of these bat girl costumes for my two daughters. The masks started falling apart after the first time wearing them. The material was so cheap it literally fell apart!!! I was SO disappointed! By the time Halloween came I had completely redone the masks and stapled the silver belt back together.I have never rated anything before but I couldn't help myself, I want people to know what they are buying.

A:
Negative
