[EX Q]: I ordered these in 2 colors....blue and purple, both of which arrived defective. The right ear piece only functioned sporadically without any input from my phone at all. Amazon is sending me a replacement pair but the same problem with second pair. Very disappointed in this product for quality control, however they were pretty great when working right. Will give it one more shot before resubmitting review. Don't buy unless you want to waste time trying out multiple pairs.
[EX A]: Bad review

[EX Q]: Really like it. This was my second purchase and it has an attractive look - would recommend all who needs one or another type of case. Well made.
[EX A]: Good Review

[EX Q]: This is a beautiful mug when full... it's the perfect size and holds enough coffee, tea or hot chocolates/smoothies for my family. The only problem was that when you wash it in the dishwasher, there are often rust spots on it! It's so disappointing especially because I paid $30 (or whatever price) for this mug. Very disappointed :(
[EX A]:
Good Review
