Question: Does this sign have an on and off switch ,
Document: I gifted my daughter with this sign for her seashore place and she absolutely loves it. It was so well packed that it seemed impossible to have breakage. The sign itself comes complete with a chain for hanging and an on-off switch.
Very beautiful and so colorful. It fits our wall perfect and we would recommend this sign to others. It came when this company said it would and the price was right. I would buy from this company again. Also the sign looks like it is made well.
I had been looking for a colorful neon sign for my music room for quite some time. I could not find one locally that I liked. Also, I was reluctant to purchase one from the internet mainly due to concerns about breakage in shipment particularly from a company located in China. Anyway, I took a gamble based on competitive pricing and favorable reviews and made the purchase. The product arrived at my door in less than a week and was packaged with lots of protective foam.
This was just what I wanted, lools great in my bar area . The shipping was unbelievable ( 4 days) . I read a lot of the reviews before ordering this and the shipping seemed to be the biggest complaint. I took a chance since I didn't need it right away and was amazed when I got a mesage from DHL it was going to be delievered the next day .
This item took over a month to ship to Florida which I did not anticipate. It had to be sent from China and got held up in customs. I found this out after I contacted the seller when it had been several weeks after the item was estimated to arrive. The representative whom I did talk to was very helpful and explained what had happened and ensured it would arrive at a later date.
This item is a great addition to any bar area. First order was damaged, due to shipping but not due to manufacturer. The item was sufficiently packed but must have been damaged en route. Notified company, had to show proof of damage thru picture. They shipped a replacement immediately. Great company to work with. Love the light
The colors are spectacular. Incidentally, before making this purchase, I contacted Amazon customer service who assured me that they would back me up 100% if there were any issues. So, take the plunge and purchase a cool retro neon light to spice up your game room.
I am so pleased with it that I would recommend anyone looking for this or similar items by this seller to order but be aware that it will take a lot longer than what they say it will.
Colours were bright and cheerful--looks great on the wall ! Service was prompt and package was packed well.
