Review: Great Warrantee - Update: 1 day after leaving my original review, Seller contacted me and sent copy of their origial responce to replace defective part that went to my spam email. Appologized for problem and immediately asked to send a replacement. Their customer service once the emal issue was resolved is outstanding. Informed me that package had been sent and the day of delivery sent a followup that stated it had been delivered and if I had any further concerns or issues to contact them to make sure I was satisfied. They stood behind their product and delivered as promised. Happy camper here now! Nice when first installed, within 6 months power supply failed. Contacted Mfr to inquire about replacement either under a warrantee or for purchase so I could continue to use the lights. Never got a responce from Mfr so they are still dead. Almost a year since my original purchase, they are expensive paper weights but not cool flood lights.
Review: Awesome Lights! - I initially bought one set for the front of my house but it wasn’t enough. I added a second set and am really happy with the result. The app is super easy to use and I play around with the colors every week or so. I’ve only had them for a month or so but I am very happy with them. I have two little girls and they get a big kick out of them. We change them with whatever holiday or season it is. So far, Mardi Gras (like the photo, Valentine’s Day (red and pink), Presidents’ Day(red, white, and blue, and now, st Patrick’s day. One of them has a weak wifi signal, but it hasn’t affected the performance. I’d recommend them to anyone who wants to add a little color to your house or other project. They’ve also made it through some pretty significant rain storms without issue.

## Questions & Answers

**Q: Can I string only 4 lights together?**
A: The unit comes with 6 lights that are strung together as a non-detachable unit, with about 10 feet of cord between each light. Using the app, you can control all 6 lights at once (same color/brightness), or have each light display a different color/brightness. Through the app, you can also link several different units together into groups, and control them all together. (I have only one unit so I haven't tried this, but the instructions are in the manual.) One thing to point out: the lights will only connect to a 2.4 GHz WiFi network, NOT a 5 GHz network. Usually it's easiest to create a "guest" account on your exiting network and designate it as 2.4, then connect the lights to that. This 2.4 GHz requirement is mentioned in the manual, but I glanced over it the first time I read it and got very frustrated until I realized why I was having so much trouble. Once it connected to 2.4, everything worked perfectly.

**Q: will they work with only a remote?**
A: Dear customer, thanks for choosing Usteller, the rgb flood lights only work with moible app with 2.4Ghz WiFi. Best regards,

**Q: can it be used without wifi?**
A: Dear customer, thanks for choosing Usteller, our GemBand smart foodlight can only be used with WiFi. Best regards,

**Q: can i extend the distance between each light by adding more wire?**
A: Dear customer, thanks for choosing Ustellar, the distance between each light can't be extended, please do not cut the cable. Best regards,

### ⭐ Worked great….until they didn’t
*by K***2 on March 7, 2026*

Used these for quite a while in our front home display & they worked fine….until they didn’t. No way to get ahold of anyone, & Amazon support methods leave something to be desired. Just hook me up with the seller for cryin out loud! I have power through out the cord, but the lights don’t come on. The SmartLife app is worthless for debugging…just general connectivity stuff that doesn’t apply to these lights. I fear these are just landfill material unless customer service reaches out to me here.
