I ordered a neon sign from Underneon and was extremely satisfied with the entire experience. Communication was fast and professional and the product fully met my expectations. I would definitely recommend Underneon to anyone looking for a high-quality neon sign!
So happy with the sign and the service. We ordered a sign for our new office and the communication from the beginning till the end was amazing. The staff is very attentive and ensuring you get what you need. 10/10 would recommend
I loved it a lot. The service was wonderful. Marta, took great care of me from the first contact, via WhatsApp. They made the necessary changes, and since I needed it urgently in production, they have a rush production schedule…
I am more than happy of my neon signs! Customer service was fast and comfortable by whatsapp and they called when the signs were ready to post. Delivery took only 3 days 😍 I would defenetly recommend!!

Mainly size, total LED wire length, and the number of individual pieces. Font choice also affects the price of lettering.
LED neon costs less, uses far less power, needs almost no maintenance, is safer, and supports digital control — dimming, colour changes, strobing.
