I decided to introduce a Betta sorority in my biggest tank, and had an aggressive female who attacked and killed other fish. I only had a 1 gallon to keep her in, I didn't have a money to spend on a lot of equipment, and I didn't really have room for anymore aquariums. I grabbed one of these from Amazon Warehouse at a steal, and as somewhat knowledgeable aquarium owner I wanted to give my impressions.
Filter Pump Noise Level: Probably the biggest thing on everyone's mind concerning this purchase. Let me assure you it is absolutely silent with very low agitation. I have 4 different sized filter pumps and this is the most quiet, albeit smallest one. There is absolutely no friggin' way for your fish to get sucked into it, the water inlet hole is about as big as a lead pencil. It has just enough movement to circulate the water through a very small charcoal filter. You don't even so much as hear water trickling because there is very little movement. The Tetra Whisper 3i is a hang on the inside style filter, and the impeller snaps onto the bottom of the reservoir, so there are no hoses. The trick is everything needs to fit together snug and tight, you really have to force the impeller housing onto the end of the reservoir to get a good fit. There is also a clip to attach so you can hang it on the aquarium and you really have to push in tight so it's stable. I adjusted it to the tallest height setting and filled the water level to the appropriate height in my pictures. If you look at them you can see I added a piece of rubber drawer liner to the clip to act as a vibration dampener. It also says in the instruction manual that you can order suction cups if you have a problem with the clip for some reason.
Design: I really like the sleek, minimalist style. It looks cool, and is a functional piece of art that is perfect for an office, or bedroom. The plastic is crystal clear, but it is plastic so there is the potential for scratches if those bother you.
Features: I got exactly what I needed: a complete aquarium in a small form factor, with a quiet pump, and an LED light. You really should get a small aquarium heater and an AC light timer A) for your convenience and B) for the fish to have a consistent light schedule. A cheap $5 rotary style is all you really need. The LED light and pump are both two prong, non-grounded AC plugs.
Other things you will need you may not be thinking of: Don't waste money on fake plants, real ones are cheaper and they help clear and oxygenate the water. You need a 5lb bag of aquarium substrate, extra filters, some kind of a hiding spot for your fish, liquid aquarium bacteria, water dechlorinator, and a gravel vacuum. You really should give your aquarium time to properly cycle and clarify before adding a fish, but I didn't really have a choice this time so I used plant clippings, rocks, and decorations from other tanks and lots of bacteria starter. You need to do a 25% water change every week and check your filters frequently.

ATTENTION BETTA KEEPERS - COMPLETE BREAKDOWN OF WHAT YOU NEED - WISH SOMEONE DID THIS FOR ME :)
Betta lovers please read..... This tank is perfect for your Betta. It's roomy but not too big. The look is modern and stylish. There are a few things Betta keepers need to do with this unit - VERY simple things. I knocked off a star because the filter is comical.1) Throw away the filter that comes with this unit. It's junk and will only cause you unnecessary issues. The filter I use for all my Betta's in a 5 gallon or less set up is the Aqueon Model AT10 (internal filter). Make sure you rotate the flow knob to the lowest setting and aim it towards the corner of this tank. It's powerful for a 3 gallon unit but if you set it up correctly the water will seem practically stagnant. I purchased this one from Petco - so I paid an extra $10 for the instant gratification. Amazon has it for much less. $21.99https://www.amazon.com/Aqueon-10-Gallon-QuietFlow-Internal-Filter/dp/B00AWV4R8I2) Purchase a Betta heater - this tank is plastic making the inexpensive Betta heater worthwhile. MAKE sure you take the temperature a few times over the first 72 hours to avoid Betta soup. I find it keeps the water at 80 degree far. $9.64https://www.amazon.com/Marina-Betta-Submersible-Heater-Aquarium/dp/B00AE23Z88/ref=sr_1_2?s=pet-supplies&ie=UTF8&qid=1467929335&sr=1-2&keywords=betta+heater3) Substrate - use something that is very easy to clean - I use accent rocks that you can find at Petco for $4.99 a bag - 2 bags is plenty (even though they are kinda small) $9.984) Get a few Silk plants - you can of course do real but NEVER plastic. They will shred up their fins. Also Petco - 3 pack for $11.995) Get a small floating log - your Betta will love it! $9.99https://www.amazon.com/Zoo-Med-Floating-Aquarium-Small/dp/B000FMWPBK/ref=sr_1_7?s=pet-supplies&ie=UTF8&qid=1467929628&sr=1-7&keywords=betta+log6) Make sure you clean the tank out - NO SOAP - before filling. And you MUST cover the gaps and feeding hole. I used some plastic (hard) from a packaged item. $07) Make sure you condition the water - I use Reverse Osmosis Water. Misc supplies - Omega Betta Water Conditioner $5.94 & Omega Betta Buffet pellets $6.65https://www.amazon.com/Aqueon-06020-Betta-Conditioner-4-Ounce/dp/B003OCXQDE/ref=sr_1_1?s=pet-supplies&ie=UTF8&qid=1467931051&sr=1-1&keywords=betta+water+conditionerhttps://www.amazon.com/Omega-One-Betta-Buffet-Pellets/dp/B01DFT93TG/ref=sr_1_2?s=pet-supplies&ie=UTF8&qid=1467931148&sr=1-2&keywords=omega+betta+food8) My Betta's thrive with Indian Almond Leaves. 1/2 leaf left in the tank replaced every 3-4 weeks. This will naturally soften the water and create condition very similar to the wild. $7.95https://www.amazon.com/SunGrow-Betta-Leaves-Pcs-environment/dp/B00HG1TMIW/ref=sr_1_2?s=pet-supplies&ie=UTF8&qid=1467930944&sr=1-2&keywords=betta+leavesTotal investment to set it up correctly is about $142 plus the Betta - This is a set up that will last you years.

I bought two aquariums for my bettas and they love their new places. These are the same bettas that sat in cups at Petco just a couple of days ago . I had the divider down in the video so they flared at each others but even when they don't see each other, the bettas are constantly swimming around, exploring every where.
The aquariums look great, clear, perfect size for small fish. The tops fit perfectly, they have cut out for the filter in the back and a feeding hole in front. The lights are bright, clip on easily. The filters are powered by small air pumps and work great.
Some people said to ditch the filter but I disagree, these filters work perfectly fine for small tanks. I keep many fish tanks 10G up to 125G and you use the right sized filter for your tank. This one works well for a 3 gallon. The air pumps may vibrate and make noise but that is the nature of all air pumps, you need to sit them flat on a solid surface or you put them on a soft piece of something to damp the vibration.
Highly recommended. I am thinking about buying 2 more but I don't know if my wife will let me. ;)
