**Update** These were perfect for the barn wedding!! Wish I took pictures, but my cellphone stayed in my handbag all through the wedding, so I never took any pictures!! :( I have however, attached a video that I took of the fairy lights when they arrived from the merchant. I have attached it so you can see the different motion options.
Bought these fairy lights to use at my son's upcoming wedding in June. They arrived quickly. I like the battery compartment on these lights better than other fairy light sets I have purchased. These compartments are way easier to open and snap securely closed. I put in the required 3 AA batteries and pressed the button to change the modes. The back of the battery compartment lists the modes in their perspective order of sequence, and the remote included, has buttons that coincide with the list on the back of the battery compartment. Awesome!! I didn't unwind the light sets yet, because I didn't want to bother with wrapping them back up, so I cannot verify they are indeed 16.4 feet in length. Sorry, but it's a 4 pack set, and all sets appear to work perfectly. In addition to the 8 different modes, you can also dim them! The battery compartment measures 2.5 X 3. It appears to be very sturdy and looks like it would keep water out when used outside. Also has a loop at the top to possibly hook it onto something. All and all I'm happy with this purchase. I will update my review after the wedding. I would recommend purchasing from this seller. :)
