BN-LINK 24 Hour Plug-in Mechanical Timer Grounded for Aquarium, Grow Light, Hydroponics, Indoor Lighting, Home Appliances, ETL Listed 125VAC, 60 Hz, 1875W, 15A, 1/2HP (1 Pack)

I purchased these timers to control my aquarium air pumps on 15-minute on/off cycles, and they’ve been working exactly as intended. Setup is straightforward. The mechanical dial is easy to read, the segments click firmly into place, and setting multiple short cycles throughout the day is simple once everything is aligned. The timers switch cleanly between on and off without hesitation. Build quality feels solid and appropriate for continuous indoor use. The grounded outlet fits snugly, and the override switch is convenient when manual control is needed without changing the programmed schedule. The two-pack was a great value and happened to be exactly the number I needed for my setup. These do precisely what they’re built for and are well suited for aquariums, grow lights, or other equipment that benefits from consistent timed cycles. Overall, dependable mechanical timers that are easy to use and perform reliably.

Great timer, and very easy to use! It comes with instructions, but is simple enough to figure out without them! I actually have bought maybe twenty or so of these, and use them in my commercial grow tents to give the proper light cycles on my plants, and they work wonderfully!!! You are able to run power off of them too, and have the power cutoff when the timer goes off. They have lasted a few years without breaking, so far so good!!!

It works great and setting the time on it is super easy and satisfying. It does make a soft ticking sound. I don’t mind it but I thought I had a mouse in my room before I figured out where the sound was coming from lol.

Should have come with clear directions and all but good quality and they work and easy to use

This was easy to use and I love that instructions are right on the timers. It’s so convenient, and better than getting out a pamphlet every time! I was able to easily set it to turn my Christmas lights on every evening til ten, and then again between six and seven am. Effortless.

Works well easy set up

It works well once you figure it out.

The timer set-up is so confusing that the only reliable way to use it is manually, to turn my plant lights on and off every morning and evening. First of all, the black on black tabs you depress for the on-off time period are almost impossible to see. This is an odd design decision. The clock setting for the timer is also confusing. I tried setting it multiple ways just to see when it turned on or off based on my settings. It started coming on at night, again seeming to be at random or with a mind of its own. I never did figure out how to set it for an 8 hour time period in the day. To my eye, the problem might be the timer-- it works randomly--it does not stick to the same time frame every day, but seems to drift. I ended up just using it with the manual switch because the return time frame had expired. It works that way, but I could just as well bought a manual switch to turn on and off my plant lights. So I would not buy this product. Worth the extra money to try another better designed product-- a tool that I can understand and that works as expected.

Once you get past the initial setup, this mechanical timer is fantastic. It takes a bit of attention the first time to understand how to push the pins and set the on/off periods, but after that it runs by itself and I don’t have to think about turning things on or off anymore. The schedule is accurate, it’s not overly complicated, and it’s a very convenient way to automate lights or small appliances.
