Easy to use mic for phone/pc/laptop. Great if you just need a small mic and don't want to spend a lot of money. Works well. Comes with velvet carrying bag. *disclaimer: I received this product for free in exchange for my honest and unbiased review*

I used them one time and pulled them out of my phone and wire went everywhere and now they do not work. Biggest waste of money and would cost me more to send back.

negative

This is the second set of tiles (100) that I have purchased for my grandson (age 4) and granddaughter (age 3). Both children get hours and hours of creative play from these amazing, magnetic tiles. He builds garages and race tracks for all his cards and trucks,, she builds castles and buildings for all hr Peppa Pig figurines! It amazes me to see what they create with these tiles giving them hours and hours of playtime! They NEVER get tire of these magnetic tiles. Even more older grandchildren, ages 8, 10 and 12, enjoy creative play with their cousins! High recommend for all boys and girls, and all age groups.

Ex Output:
positive
