USB dongle did not work upon arrival of product. Called company and they said it was a warranty issue then heard nothing. Waited two weeks for resolution. Finally returned it to ecogrowhawaii.com. Still waiting for a refund. Bought this light over a month ago

para crecimiento de mis plantas interiores

Easy to use. 3 Options available for connecting them to your stand. Operate independently of each other.

**UPDATE**: I reached out to them and spoke to Harriet. They provided me with a new adapter and my light works again. The customer service was excellent.

This was a great light for my plants indoors. It worked well until it just died on me today. I went to go see my plants and see the light is flickering/pulsating. This was only a month of use as well. Very disappointing and I don't see anywhere for a warranty or replacement.

I have a 4 tier indoor greenhouse and this kit attached to each level perfectly! My plants are loving it and thriving! The timer has 6hr, 12hr and 18hr options and seems to be very accurate and easy to change as it illuminates the corresponding light/time you habe selected. You can cycle through different light spectrums on another button as well as different brightness Levels on another button! The cord length is perfect for my set up! I am very happy with my purchase and for this price, will be buying more for my big greenhouse! It's light weight, and easy to set up. It comes with mounting screws sticky tabs AND plastic Zip ties depending on your needs, i used the zip ties to attach to a small chain to be able to adjust height and then used just the zip ties once it got up to the highest I can set it in my area.

Exclent light very powerful very impressed when I first turned it on quality built product will be buying more in the near future
