no instructions on timer mode of operation, whats with that?

These worked once, for about 15 min, then quit. Do not recommend.

They were great for about 30 minutes then quit working. Cheap Made in China crap.

Light String is Disappointing ! No wall plug for power, has an USB Plug requiring buying a 5 watt Adapter, can be pricey, & MUST have to power the lights. The REMOTE is Useless. No Instructions, not told to remove small clear blocking tab from WITHIN the Battery Compartment, which is difficult to Open to remove that tab & to change Battery. I tried 3 Batteries 1025.... & REMOTE still NOT WORK. Can NOT turn ON or OFF or program any of the 8 Buttons to change the Flashing Modes, which seem ALL the SAME ! When use the Button Switch ON the String, has NO Steady Light, ALL FLASH, which is annoying. So if mount the light string outside or away, can NOT use the REMOTE for On, Off, or change the "8 Light StyleS". Do NOTl Buy !

So tangled I could not use. I was extremely careful with second set. Same problem.

Very lightweight bare wires. Don't waste your money.

Just received these, very thin exposed copper wires that love to tangle. I wouldn't buy again.
