[EX Q]: After reading reviews, I thought I would order 2 sizes up. Normally I'm a L/XL, so I purchased a 2X figuring it would fit! To my surprise, the shirt was way too small. It fits my sister who is a size small. The material was not cotton as I thought, but 95% spandex. I'm very disappointed as the shirt is very cute. Instead of returning it, I gave it to my sister. I would recommend ordering 3 or more sizes up from what you normally wear.
[EX A]: negative

[EX Q]: My cats are indoor, but I keep the windows and doors open, so fleas do have the ability to get in the house. One of my cats was starting to show symptoms of having fleas, and I opted to try this vs a visit to the vet to tell me he has fleas. Did some research, and gave this a try. I'm still on the first application, but flea issue has subsided. Also, not as smelly or greasy as other flea medicines.
[EX A]: positive

[EX Q]: We use Ok Yuk jetted tub cleaner each time we use our jacuzzi tub. Yes, it's costly to do so, not only for the product but for the extra water that we have to use to flush it out, but the lines in the tub are clean, the water that flows through stays clean and we can be assured that things will run smoothly for years.
[EX A]:
positive
