Placed one at the handlebar top for climbing and one in the drops to activate weeeeee. Easy set-up but just note that the clear plastic thingies that come in the package are one of the options for mounting so don't throw them away thinking it's part of the packaging like I did. It sucks these are throw-away items because you can't replace the batteries. Come on SRAM, do better.
The blips are not compatible with first generation 11-speed Sram Red Etap!!!!
They wok perfectly. My only issue is that you cannot change the battery. Once they run out you throw them away. I hope I get several years out of them. But let see.
