[EX Q]: I didn't know what to expect when I saw this. I love travel books so anything about travel experience I will give a go. As soon as I started to cry with laughter reading about the kangaroo incident as a child I was hooked. So funny. This man certainly has had an interesting life.
[EX A]: positive

[EX Q]: I need something to hold my new prescription glasses - I wanted to protect my Coach glasses and this was perfect. Double protection and great to toss in beach bag
[EX A]: positive

[EX Q]: Much cheaper to just get this instead of changing for new ones at a third of the price. I'll definitely be going through more than 3 more oil changes, so this was the best move. Didn't notice much performance increase until it was super hot out, my car didn't skip a beat. Keeps engine running cooler
[EX A]:
positive
