Since this tank comes as a kit, I will rate each component individually.
Tank: 5/5
Glass is good quality and thicker than I thought it would be, clarity is good, seams are nice, top edges are smoothed over and clean. It also comes with a closed cell foam mat to place the tank on which is a nice addition. (Be sure not to throw this out with the packaging!)I wouldn’t change anything about it. This tank alone is worth the price.
Top: 3/5
Flimsy plastic, but it serves its intended purpose. The hinges are nice and mount securely. It may not do much to help evaporation, but it will keep your fish in the tank. I didn’t use it for my application, but it’s a nice addition to a rimless tank. I’d like to see it made out of glass.
Filter: 4/5
The filter is cheaply made, but it works. It’s basically just a tiny pump with a sponge attached over the intake, which is perfectly adequate for this size tank. It provides good mechanical and biological filtration. The noise that other reviewers are complaining about comes from the air intake on the return which is not really necessary. Simply plug the nipple where the tube attaches and it’ll run near silent. It would be nice if they included a second return without the air intake, but the one it comes with is easily modified.
Light: 2/5
It works, but the armature is flimsy and it is not very bright. It could be okay for a betta or something, but it is still not really bright enough to show off the tank as well as I would like. It definitely would not support even the lowest light plants. If you plan on keeping live plants in this tank, you will absolutely need to purchase a different light fixture. I did not use the included light after the initial setup of the tank, but it was helpful while aquascaping since it’s so small and stayed out of my way.
Overall: 5/5
I really only purchased this kit for the tank alone, and I am very pleased. The tank alone is more than worth the price of the kit, so everything else included is kind of a bonus.
The attached picture is my tank 2 months after initial setup. The plants are Staurogyne repens, and the livestock are Neocaridina davidii (freshwater dwarf shrimp). The light pictured is not included with the kit.

Sleek and beautiful
Amazing. My new favorite tank. I have always been looking for a pure glass tank with no black rims and I finally found it. The filter is a little funny and it’s huge. But I don’t mind it. Filter is strong even on the lowest setting. Going to have to wait until I put my fish in to see how strong it really is. It doesn’t come with the cool water fall feature I was bummed about that. Also taking off the stickers is insanely hard for no reason lol. Literally took more time taking off the stickers than actually setting up the tank. That’s the reasons why I rated it 4 stars because it isn’t perfect but I love how the look. Also I forgot to mention there is no off/on button for the light you have to physically turn it off which can be an issue for someone who hides there wires behind something

Perfect nano tank, filter isn’t ideal for small nano fish

Great tank, the glass is thick and the curved corners make for an awesome view and a great addition to a Nano aquascape.
Not sure why people were complaining about the lid, Ya it's flimsy but why would you want something thicker? Its more then enough and gets the job done and it's looks neater being thin and light weight, it also has a large gap near the back, because it's for easy filter maintenance, you don't have to remove or open the lid to get at the filter. The lid hinges are a great design, I love how you can open it to feed the fish, or you can easily slide the clear plastic out of the hinges, to clean or perform maintenance on the tank.
The included light is definitely subpar. It's better then nothing for sure but I get why people were complaining. 1. It's not really bright (this only really applies to growing live plants) and 2. No on and off switch (yes you can use a timer). Other then that I mean it's ok as a spare light, or maybe you can find another purpose for it.
The internal filter is so far so good. The flow is kinda high for a Betta even when it's set to low (yes it has a flow switch) but if you angle the outflow head to the side of the tank it blocks most of the flow from disturbing the Betta. On high it's actually quite a powerful flow, good for cycling the tank before you add a fish, or shrimp etc..
The way it has a built in air bubbler is really neat, I don't use it because I have a Betta , but I did try it out, and it works awesome , however the filter can only be about 1/4 inch under the surface of the water or it won't blow bubbles (guessing you might be able to fix that with a longer airline tube)
Really the only draw back to the filter is the lack of filtration it can provide and how fast it clogs. Itsreally small which is good for aquascapes, though the size of the media basket cant hold really anything that big. I got away with using bioRings smashed in half placed under the stock sponge. Its definitely better this way over stock, but still not really that good. Wish the filter was slightly bigger in length for more media to fit.
I took a star off because the way they include all the extras (light, filter,lid) in the tank, they siliconed a box with all of the above mentioned to the bottom of the tank glass and was really hard to remove , also felt like I was gonna break the tank trying to get the box out as well as remove the silicon from the glass (see photo)
Overall super pleased with this tank! I will update review after a few more weeks. But so far really decent value for a nano aquascaping tank that would normally be alot more in cost from a dedicated aquascaping store.
Update , Sept 26 ,2019.
Tank is still excellent , no issues with anything since I've bought it. I've changed the light a couple times till I was happy with one I found (nicrew flexible clip led) and I changed the filter to a azoo mini hob filter that is way way better then the stock one this kit comes with. Overall still amazed at the quality of this little tank!
If you liked this review or found it helpful , I would really appreciate it if you give it a like! Thanks
