I never write reviews but look at them for everything. This unit works perfect with SONOS and being able to run Apple TV, Fire Stick, or Cable to a 4K projector that does not have optical input. Took me awhile to find the right switch and this one does the trick. Full 5 channel surround and I confirmed my projector is running 4K.

Ex Output:
positive

Ex Input:
I really like Pippa's writing. This sci-fi slash fantasy combination has me hooked. Cannot wait til the third book is released. Plot keeps you guessing about what challenge will come next, and how will the character grow with it. Please keep this series coming...quickly preferred. ;-)

Ex Output:
positive

Cute little fountain. My bird bath is entirely in the shade and it squirts up 8". If you put it in your bird bath, it will empty it in 30 minutes. Great entertainment.

Ex Output:
positive
