Thank you for viewing! ☺︎ Flashing and app connection confirmed. Includes the main unit, box, instructions, and strap. Purchased in 2023 and used about 6 times at live concerts, and has been stored in a dark place since then. I am selling it because I am no longer a fan. There are several small scratches on the dome part of the main unit. Please be aware of this if you are sensitive to such things. (See photo 5) ⚠️Batteries will be removed before shipping⚠️ ■ Immediate purchase is OK. ■ No price reduction.
