    Connectivity Issue

    • Written by from Pascagoula

    Pros: Under Armour is a great company and has great customer service. Great concept as well. Very easy to use and has lots of detail regarding intensity and heart rate. Keeps motivation going when it usually runs out.

    Cons: Doesn't work. Bluetooth connection drops in and out. Sometimes will not connect at all. UA has replaced the unit twice. The second is in my gym bag collecting dust. I don't want to deal with it anymore. I am somewhat technologically savvy and can get things working very well but this is not a good product considering all the great things UA puts out

    I can't say enough positive things about the Armour39. What Under Armour has done with this product is unlike anything else on the market. It really makes me push myself to the next level to achieve my WILLpower goals. I will continue to use my A39 for each and every workout from here on out!! Thanks Under Armour!

    This thing takes training to another level. Now I can see how hard I am working simply during the workout and get a total score (Will Power... Love it) for my entire workout. Recommend this to anyone who trains

    As a professional sports Strength and Conditioning Coach I use the Armour 39 with all my athletes for maximal results. This is a great tool to challenge yourself, break personal goals, and work to achieve maximal fitness through heart rate tracking. Best in class from a brand that is best in class.
