  • Seamless look when done correct, read instructions!
Color: Dark grey Size: 37" × 18" (94 cm × 46 cm)
If you follow instructions this is super easy to install, you have to use a bit of elbow grease when connecting the magnetic tracks to the top piece but aside from that I found it easy. It only took me about 30 minutes or less to get it put together. It fits just fine as well. If you have a filter where you need to cut around, I suggest putting the final adhesive clips on the last step on either side of that so that it will hold flush on the one back magnets. I feel the quality is just as expected and good value for what you pay, I kept all the leftover pieces for future fixes if needed. My tank is 20 gallon and the width of the mesh was perfect to cover the length of my tank, I just had to measure the width of my tank and trim the mesh to fit that. So super easy. I feel like this will serve its purpose perfectly and I like if you measure it well it looks pretty seamless and nice, not an eye sore which I was worried about. It also does not inhibit my light either which is great. Will update later if it doesn’t stand test of time. For now though, super pleased! ... show more

  • Great for reptiles
I had recently bought a 40 gallon tank stand that you can fit a 20 gallon tank on the bottom. I measured the tank and decided that it would fit. Lo and behold when I put the stand together, the tank slides in perfectly... Except for the lid. It was a millimeter off and I didn't have any ideas to replace the lid. I have a small corn snake in it so it had to be escape proof. This lid definitely delivered a great seal. It was very difficult to put together, especially putting the last rubber row on the track, but I think my thumbs will forgive me since it came out so night. I was still able to but a light directly on it and put a fogger through the mesh. Now my snake is safe and I'm happy. ... show more

  • Works great
Color: Dark grey Size: 37" × 18" (94 cm × 46 cm)
When my led light went out on my fish tank cover. I was trying to figure out how to use one of the LED strip lights that goes over the tank. Glad I found this. You just clean and dry off the top. Put the magnetic strip down first, and trim to fit. Then you put the plastic screen cover over the top. Press the snap in pieces. Left, right, back then front, while gently stretching the fabric. Not too tight or it will pop the magnetic strip out of place. Pop the corner pieces on. Then trim out sections for air lines and filter. I cut a section on the front so I can flip it up to feed the fish. I would not trust it to be strong enough to hold a cat above the water, like in one of the photos. ... show more

  • Worst tank lid ever. Won’t stay on
Color: Dark grey Size: 37" × 18" (94 cm × 46 cm)
First it was a pain to get on. Second the magnet refuses to stay connected. I had it put together for 10 minutes and it was coming up. It took forever to put together correctly and the instructions were no help. It says it’s pet proof and there’s literally a cat laying on it in one of the pictures. My maybe 5 pound kitten put her two paws on the top of it and fell in. The entire thing has fallen into the tank twice since I put it together over the weekend. The only thing I like is that I can cut it to fit my filters. I will no longer be using this as I have to put a box over top of it since it keeps falling down and isn’t doing it’s job. ... show more

  • I love this so much I plan to purchase another!
I love my little rimless bookshelf tank, but it's a betta d**th-trap - I've lost several little buddies to jumping out. I was so upset, I promised never to get another betta. Until I did. This time, I vowed that I wouldn't let anyone jump and I've kept it sealed with plastic wrap. An effective, if unsightly, solution. Enter this little mesh lid kit. Though it doesn't come with directions, there is a video under the description of the product. This seller believes in you - and so do I! It was so easy, and even though I made some mistakes in cutting, it still works perfectly. I included pictures to show how I dealt with the two lights and a hang-on back filter. The magnetic strip is very powerful and sturdy enough to create a little "bar" in front of the HOB filter. It seems very durable, but will probably wear out in a couple of years. That's why I want to get another kit to have on hand -just in case. ... show more

  • Do not buy
Color: Dark grey Size: 37" × 18" (94 cm × 46 cm)
The quality is very bad and no matter how good you try to reassemble this it would never work out. Even after a week, I can see that the screen is also not good than being batten down. I would not buy again.

  • Great quality for smaller tanks
Color: Dark grey Size: 37" × 18" (94 cm × 46 cm)
Changing my rating not because of quality but because once the magnetic strips get used for a while they loose their magnetic charge and fall into your tank just need a stronger magnetic piece to hold the netting

  • Great!
When I read the reviews on this a good portion of them said that it was hard to put together, but I actually found the process really nice. I enjoyed putting everything together and so far it seems really sturdy. Especially for the price and that fact that it is totally customizable. The thing that almost made me change my mind on this was that I was unsure if I could put my lizards heat lamp on the material. But it is holding up nicely. 10/10 I would purchase again. ... show more
