[EX Q]: I carefully read the book Overthinking and learned a lot from it. Which is playing an important role in my real life. Moreover, with this I have been able to change my self-esteem and mental attitude to success. The book changed my life. Thanks to the author.
[EX A]: positive

[EX Q]: The bands work great and I like the different colors which make the Fitbit more versatile. I wear my Fitbit all the time so I am able to change the band to coordinate with what I am wearing. Great price and made very well. I have had mine for about 2 months now and have had no problems. Received the item in a timely manner!!
[EX A]: positive

[EX Q]: I bought these sets of wheels because I didn’t like the ones that came with the original chair. I have hardwood floor so I didn’t want the wheels to scratch up the floors. These wheels have no edges, making movements rather smooth. Very satisfied with these wheels.

positive
