Question: My lights were working great for a while. Now they just flash red. Any ideas what that is?
Document: We bought this for under cabinet lighting in our kitchen and they are just great ! I setup  3 sets easily and they are perfect !Pros : love the control over the colors and light intensity with the remote - as a bonus, any remote works with any set. All lights are still working fine after one month. The price is unbeatable as well.Cons :  The user guide is non existent. It took my teenage son an hour to figure out the connections but after that, setting up was a breeze.
I bought for $ 25, the multi colors lights,  and the lights arrived red. I wrote to them but they never responded. I still have the unused light in the  box, because i dont need it in red. Losing  $ 25.00 it's not funny.
I originally put these lights in the hood of my aquarium to accent the color, but it wasn't bright enough, so I moved them to my desk for accent lighting. After moving them and only having flexed the strips a limited amount, a few of the colors stopped working in some of the leds.
Even with connectors, you may have to flip the strip to get it to work. If the second strip glows light red, you need to flip the connector.The strips are peel and stick but not all of them stuck. Easily fixed with some double-sided tape.
Great lights. Brighter than I thought. I use them for my DJ facade and they work nicely.
Great lights especially for the price. I plan on getting more for my kids rooms because they think these lights are the cats meow
These lights work great! I had no trouble at all hooking them up and sticking them to the back of my TV for some bias lighting. I love all the options and everyone who comes over thinks it's awesome.
the lights work perfect. easy setup, i order it regular mail, it came a few days later. the color pattern is great. but for some reason my remote control works for my LED color change light blubs.
Let me just start by saying that I looked everywhere for something like this.. and this was BY FAR the best price I could find. The lights look great, it all connects very easily and the remote is oh so convenient.The entire package is very versatile and very well worth it.. HitLights rocks!
This lighting system is a great product, I would give it 5 stars if it wasn't for a few different things. The sensor is infrared, so you have to point the remote in the general location of the sensor. Sometimes it takes a few times to get the sensors to line up and the lights to work. Another thing that could be improved is the cable distance between lights. The lights come with a power cable that is maybe 8-10 inches long.
Answer: yes
