AQQAAquarium Wave Maker,3W/5W/10W/15W Suction Cup Fish Tank Single Powerhead Pump，110V/60Hz Ultra Quiet Submersible Circulation Pump,360°Adjustable For Freshwater Saltwater Black

So this review might be a little lengthy, but there are quite a number of little experiences that happened with this purchase.First off...the gear. EXTREMELY quiet and powerful. Easy to install. Simply attach the suction attachment to the WAVEMAKER, place it into your tank and plug it in. Keeps the water circulating and oxygenated.So, from my point of view, something must have happened in transit when I first acquired these a little over a month or so ago. I had purchased two of them for my two, 100 gallon fresh water fish tanks. When they came in the first time and I plugged them in, they were shaking, rattling and clearly defective. Mind you, I had read all of the reviews and seen such high customer satisfaction ratings on this gear and this company, so I was a little baffled as to why my Wavemakers were making so much noise and struggling to operate properly.After fidgeting with them for a couple of weeks, my return window closed at Amazon, and needless to say, had surrendered to the fact that I was stuck with defective, broken equipment that I paid 40 bucks for. Subsequently, when asked to post a review about the product, it was not very positive in my verbiage and I relayed my frustration and dissatisfaction with the product.To my pleasant surprise, the vendor reached out to me through Amazon chats and was very adamant about wanting to rectify the problem and make things right. I was a little skeptical at first, but they were indeed very genuine in wanting to help me resolve this issue and stand by their product. In the end, they sent me two new pumps that are working quite nicely and are what I was looking for.AQQA is a great company with great products, and have their customer satisfaction as their top priority. which is truly a breath a fresh air to see in the online shopping world. TOP MARKS ALL AROUND!

I tried buying the lowest watt one I could find because i just want a gentle flow in the tank, but nope. I have a 40 gallon tank & it's too strong for my tank. I don't feel like taking a video to show how powerful it is, but if you're looking for a gentle flow is a tank size like mine this isn't the one. However, a great choice for a much larger tank of you are just looking for a little flow.

Its good for about a year then the magnet stops working and the thing spirals out of control. Either, its faulty after a year or its good for a year!! Works great.!! Really good circulation for my 120 gallon tank. If the magnet doesn't fail after a year the device will last longer

Good product and a reasonable price

This wave maker was exactly as described. Low noise, strong suction, powerful current & a good all around product. I got the 3 watt motor & it was just way more powerful than I was looking for though. I've got a 20gal tank & I was just looking for a light easy current to keep things circulating & keep my floating plants away from the filter. This thing was like a typhoon in my tank. My fish were having a helluva time just swimming. I need something with a step down setting I think. You may too if you're like me.

Junk. Broke after less than two months.

Started out really quiet. Then at times makes a rattling sound then eventually get quiet. Otherwise, works decent .

The media could not be loaded. Using this as a water agitator in my 10g salt water sump/refugium system with Chaeto. Size is perfect for my needs but more powerful than what I prefer so I did what the other reviewer recommended. Wrapped the power head with a piece of filter foam to tame the flow and it works! As a bonus it also catches unwanted little Chaeto pieces floating around the sump. Can't hear the motor with all the other equipment noise in my system. Suction strength is just right for the power and size. Connected it to a timer synced to turn on when the Chaeto light comes on. What more can you ask for at this price? Only question is durability. I'll be happy if it lasts even half the life of the other power heads in my display tank.
