It's great for food delivery and driver jobs
Size: 7''x3''
My husband got this for food deliveries and uber/Lyft. The app let him add several texts. I believe he added 4. He was able to design it how he wanted it. It seemed fairly easy and I liked how it looked. The words would scroll over, like... Uber eats, etc... It included a big roll of strong red tape. The led screen product is charged by wall plug, phone, or the car usb phone charger. I think it was a spectacular product. I thought it was limited to 4 letters since it is small in size.

Very good LED sign for cars, studios, desks, etc
Size: 1PCS 15''x4''
Great! Item really stands out. This LED sign by Ray home features way more than just devil eyes. There's a lot of pre-built templates for every gig work there is out there for your car. Item was described. A bit dim during the day but at night really shines stands out. You can customize it with uploads withdrawing. You can have programs that animate between the different signage. It's a great product for a car or for your home. To be honest, I can see a lot of uses for this. High quality design. Easy to work app. The adhesive is great for glass. It's reusable plus it comes with strips. If you want to mount it permanently not on glass. Overall a great deal.

Use DUCT TAPE!
Size: 7''x3''
I actually ordered the window signs for cars. Even though it shows different, I got what I ordered. The problem comes in where it shows where they just stick in the window. WELL, THEY DON'T STAY FOR LONG. I drive for Lyft and Uber. I want those signs and need them to stay where I put them. The stuff they send with the signs is junk. USE DUCT TAPE AND BE DONE!
