Don't wait..
I wish I hadn't waited so long to purchase this. I have already ordered a second one to convert both fobs. Full disclosure I did not assemble it, shout out to my bf, but he said it was not bad at all… I got to witness the battery and snapping it closed and it does take a little bit of work, but overall he agreed to do a second one for me so it couldn't have been that bad.
We had no issues with the button sticking. And everything works perfectly. Also, the color is so bright and hot pink and it's beautiful.
