Review on Enhance Your Pool And Pond Experience With LOFTEK Submersible LED Lights - Waterproof, Color Changing And Remote Controlled (8 Pack) by Anthony Epps

Two of the units rusted completely through within 4-5 days. Per the instructions, I tighted the lids as much as possible, they were properly seated in, "the groove". Placed all of the lights in our (saltwater) pool on the first night. However, as you can see by the photo, they rusted very quickly and became unusable.Pros: - When we first got them, they were bright and worked great - Remote control works without any issuesCons: - Rusted almost immediately - No details on what the settings on the controls do, had to discover by testing - Suction cups were 'iffy', two of the units stayed attached to our pool walls, the other two sank to the bottom within about 2 hours (note: the two that sank were not the rusted ones, one of the ones still sticking to the wall rusted and stopped working which is what drew our attention first when it wouldn't come on)Returning for refund.
