The wireless adapter is great when it works, but it has always had lot of stability issues.
Expect a random greyout/blackout about once an hour, and depending on the game you have to completely shut down VR and even restart the vive wireless app to get everything working again.
Mine finally started dying every couple of minutes after 1-2 hours of use, so finally got some pulleys instead. 
tl;dr if you get one make sure it's brand new and has a 2 year warranty
