Rated 5 out of 5 by from Brilliant! I bought this Wahoo ANT key to enable me to use my Tacx Genius with the app on my iPad. I purchased it with apprehension that it might not work. My worries were unfounded as it worked fantastically! Brilliant piece of kit!

Rated 3 out of 5 by from Old tech Wish this was made in a lightning end because as it is now you have to buy another $30 adapter to use on a newer IPhone.

Rated 5 out of 5 by from Satisfied customer This product works well for what it is intended to do. I am very happy with its performance and it worked right out of the box. No issues what-so-ever.

Rated 3 out of 5 by from Doesn't work with virtual trainer. Wahoo key sees all bike sensors and the Kickr, but only allows free ride mode on virtual trainer. This is disappointing, since my husband really wanted to ride the routes with video and that was the whole point of the purchase. Giving three stars because we honestly don't know if the problem lies with the wahoo key, or the virtual trainer app. (Using this with 1st generation iPad.)

Rated 1 out of 5 by from such an obnoxious solution to ANT+ on the iPad I have an iPad Pro on my trainer stand. I usually just keep the charger plugged into it. I hate that I have to unplug the iPad and plug this contraption into an adapter to get ANT+ working. Apple should really consider building ANT+ the the tablet and eliminate the need for a dongle (all Samsung Android Tablets support ANT without an adapter!). And buying this for $60, and the adapter for another $30 just adds to the cost unecessarily. Some of the devices I use do not support bluetooth. I really don't want to have to replace my training hardware just to get access to the apps on the iPad. /frustrated

Rated 5 out of 5 by from It just works... Bought this about a month ago and it's great. Plugged into my iphone or my ipad and Bang all my apps just picked up all my sensors within seconds. So simple, with no issues so far...

Rated 4 out of 5 by from DOES THE JOB Bought the Wahoo key to be used on my iPad 3rd generation with VirtualTraining application. No problem at all, the applicaton recognizes my home trainer, cardio and cadence sensor on first connection. Nothing special to do. A true plug & play! Not 5 stars because I feel it overpriced!
