My old light burned out and I couldn't get a bulb to last much longer than a month. This is a Godsent! Love the timer. It could be brighter, in my opinion, but well worth jt.Looks great and is easy to install; the suction cups hold on well, and I haven't had any issues with submerging it. The light/glass doesn't get hot either, so it's safe to put wherever!I bought this for the hood of my aquarium, since the LEDs it had that were built into it stopped working and I couldn't find a replacement.Fresh out of the box everything works perfectly. Got the 19 inch one for my 30" wide - 18.5" tall aquarium. I was worried it wouldn't be big enough at first but it lights it up really well. Big fan of the different lighting and brightness options it offers, they make the aquarium look really cool.There's a few cons, however: first thing i noticed is that it did feel a little fragile, I feel like one bad drop and it's game over for it.Some other minor inconveniences include the remote working at just certain angles, and the suction cups being kind of hard to get to stick.TLDR; great product specially for the price, however it does have a few flaws that won't be nothing but a nuisance.Will update in the future if anything happens to it.I needed a light for the inside of my fountain since the led’s that where originally there burned out. Pretty decent little light! I bought the 7” version. All in all not to bad!Bought four of these in various sizes to replace the led lights that came with our tanks. These don’t grow algae from light exposure. All the features work great, set up on a timer and the colors are true.Fun for fish and kidsAdmittedly, I was skeptical purchasing this light. My concern was that it would not properly adhere to the glass and my fish would be traumatized. Boy was I wrong. This thing adheres like glue....it's been a month and I've had no problems. Would definitely purchase again!Light has great suction...you can change the colors of the light and even have it randomly change colors..price is fairWould buy this again! Perfect!
