I recently tried out these solar pool lights, and I have some mixed feelings about them. First off, the solar panel does a fantastic job of providing a nice, bright light, which really enhances the overall ambiance of the pool area. However, when it comes to the underwater lighting, it doesn't illuminate a large area,it mainly adds color to the pool rather than providing any significant brightness.I haven't had the opportunity to test the app yet, but I truly appreciate the convenience of not needing to manage another remote control. If you are not tech savvy, the lights can be controlled manually from the solar panel.One standout aspect is the magnetic underwater attachment. It's strong enough to hold firmly against the wall of my above-ground pool, which is a definite plus. However, I've noticed that when the kids start roughhousing in the pool, the lights do tend to become detached. This isn‘t just a problem with these lights; I’ve experienced this with other magnetic pool lights as well. What‘s different here is that my previous lights had the magnetic mount glued to the interior of the pool, whereas these do not require glue. Unfortunately, this means when the lights detach from the magnet, the holder falls to the ground, which can be an inconvenience.Overall, while I enjoy the aesthetic and the solar functionality, I wish the underwater lights provided more illumination and that the attachment system could be improved to withstand more vigorous play.
