[EX Q]: These are very large mouthed straws. I thpught they were regular size, but they are more of a smoothie or larger type of straw. I'm not sure who needs a straw this large.
[EX A]: negative

[EX Q]: Well I received this product Monday, it’s friday and won’t turn on anymore. It was wonderful for 4 days, but like I didn’t spend 30-40 bucks on this for it to stop working. I’d like my money back, considering my old heating pad lasted 3 years.
[EX A]: negative

[EX Q]: The book has a sampling of stitches, but not that many. And the author admits to searching out old embroidered pieces and cutting them up and/or adding more stitches to it. I don't agree with that. To me those are heirloom pieces, not something to be butchered so you can say "see what I did".
[EX A]:
negative
