I have worked with Guangzhou Grandview Manufacturer a few times for the purchase of double-sided digital scoreboards for my New England Sports League. we have been VERY pleased with the products. They are very well made and priced very reasonable. we will continue to work with them for all of our scoreboard needs. I highly recommend them and give them a Five-star rating! ⭐️⭐️⭐️⭐️⭐️
