I have a food trailer and I always had to be yelling at my clients to come and pick up their order, after buying this system it was very easy for me and for my clients they really like not having to worry about missing their turn, now my business looks more professional and customers can wait for their orders in their car encouraging social distancing so they feel more secure and my business keeps running. It is a very good product, easy to use and the signal range is long, it does not matter if they enter the building next door, they still receive the signal, I love how practical it is, I am very happy, I highly recommend it for any business in that customers have to wait their turn. It makes my business look fancy !!
