We bought 2 audio guest books to up our Photo Booth business. First I would like to say Sunny Lee has been fantastic. They are quick to answer and are always friendly. We are very satisfied with how the product arrived (quick as well. Only 10 days to arrive for us) Tge quality of the phones are better than I expected as well. If you are looking to expand your business this might be your next purchase. ⭐️⭐️🌟⭐️⭐️
