Indoor Mechanical Outlet Timer, 3 Prong Timers for Electrical Outlets, 24-Hour Programmable Plug in Christmas Light Timer, ETL Listed (2 Pack)

The directions are easy to follow. The timer is accurate. Works very well. It is small enough to not block the other outlet. I would recommend to anyone. We used it on the light to our fish tank.

Work great. I use them for my fish tank and reptile enclosures. Difficult to fine tune but better than turning lights off manually.

This product is definitely worth it for the price. However, the timing is not exact. I will set it for the same time every day and it'll vary by 20 minutes or so. Still works well.

Excellent! These timers are better than most of the others --- the outlets are on the SIDES! Not the front! That's what I was looking for!

I originally gave this product a 5-star review. The setup was easy, the schedule options were solid, and I liked how straightforward everything was. I bought two of them to control my aquarium light and CO₂ injection, and for the first week or two, both worked exactly as expected.But then I noticed my CO₂ wasn’t turning off at the right time, and the drop checker was starting to go yellow. I checked everything and realized the mechanical timer dial on one of the plugs was spinning way too slowly — enough to throw off the entire timing cycle. It still “works” in the sense that it turns on and off, but the rotation is so off-schedule that it’s basically useless for automation.This nearly wiped out my plants, since CO₂ running without light can gas out the fish or crash pH fast in a planted tank. If I hadn’t caught it when I did, I probably would have lost a lot more.The second unit is still working fine, so this may have just been a defective one. But when you’re depending on these to run something sensitive like a solenoid, even one slow-spinning unit is a big problem.Setup: Easy, plug-and-playScheduling: Simple but clearIssue: Timer dial on 1 unit spins way too slowRisk: Threw off my CO₂ cycle and nearly crashed my tankIf you’re using this for a lamp or a fan, it might not matter. But for critical systems like aquarium CO₂, this isn’t something I’d fully trust without daily oversight.Thanks for reading, hope this review helped.

Works as described

I bought a two pack of this product. One is working fine for Christmas lights no issue. It doesn’t come on at the exact time it says it will. Both of them are about half an hour off. But that doesn’t bother me too much. My issue is one of them made a weird annoying clicking sound for about 24 hours, and now the lights won’t turn off. Obviously, I can manually turn them off, but I don’t know why the timer stopped working. I have literally only had them plugged into the wall for 36 hours and it is already broken. Also to me the dial on it is a little confusing. They have a sun and a moon icon but I was tired and it took me way too long to figure out how to send it to the time I want. I wish they had an a.m. and p.m.
