It’s no problem! I was able to find the bundle I bought last year, but Amazon says it’s currently unavailable.

I did however find this one, and it seems like it has really good reviews! It also comes with that lil plastic piece that holds the sensor bar so you can put it on top of your TV! Doing that stopped my cats from messing with it.
