This Fitbit-Zip was small, convenient and affordable. I ended up giving them away to friends, who like them, but they weren't working for me. My problem was that the information was too difficult to read. I am visually impaired and needed something that would either light up or have more contrast. Oh well.
I bought these two for my daughters. I love the simplicity of the trackers. It makes recording activity and calories burnt much simpler. The fitbit application and website sync with many other weight loss and activity websites and has become instrumental in my body improvement program.
I love my new fit bit. it is small, uploads automatically with my computer or cell phone if connected. I like being able to compete with my friends on steps and it motivates me to take a few more if I need to!
I just did not like the product. It didn't work they way I thought it would I returned the fitbit
Does increase my daily activity by reminding me that steps are being measured. It does not work with my iPhone 4 but I expected that based on product description and reviews.
I like the Fitbit - seems to work and accurately reflect what I actually did that day. I don't like the fact that I have to strap it to me and keep up with it.
Love my fitbit! I lost my first one and was 'lost' without it! It helps motivate me to get in my steps and work to the 10k per day! Highly recommend it! Only downside is it can get lost easily.
My husband and I purchased the two pack and now compete daily to get our 10,000 steps. These little guys are great motivators to get you moving. The website is helpful as well and I love the pairing capability through MyFitnessPal app and website.
I bought this for my wife and mother-in-law. There was good savings form buying the two pack. Fitbit customer service has been great as well. Both love this device and use it daily to help them meet their fitness goals. I do wish this item was waterproof, be careful not to let this go thru the laundry with clothes, it will make it out most times, but not all.
