Kept the water from freezing but pain to clean
341000
Helped get our chickens through the freezing daytime temps of winter. It was a warmer winter this year in Michigan so it hasn't really been tested too hard though. Pain to clean and it is 'always on' no matter the temperature. Price point was good for what we got.

Nice sturdy bucket, but found water frozen during the first cold snap of the year.  I'll be returning it.

One of the valves had a rough spot in it that you can feel drag as you turn the cold water on.

Update: nearly impossible to completely empty the tank without scratching the acrylic sides. It was a pain. Still would buy again I would just use a different substrate.

I purchased this filter system for a relative headed to South America so she could be assured of clean drinking water. She tried it out before she left and reported that it seemed very difficult to suck the water out using the provided straw, even squeezing the bottle as instructed. Also, she said the capacity was much smaller than she expected.  Based on her experience, she decided not to take it on the trip, instead using another product, a filter straw that can be inserted into a standard water bottle. I don't think that solution will be as effective in providing clean water free of contaminants, but will be easier for her to use and more practical on her trip.

This gets the job done but it takes a long time; kind of awkward draining the water out of it.
Bottom line - it's somewhat easier than ice cube trays and you will have ice a lot quicker than if you rely on waiting for your freezer to make ice cubes.

The water comes out better and cleaner than expected. It is a pain to remove filter and let it run for a few pitchers but does the job. Much cheaper than buying bottles daily

Built well and keeps water cold but the metallic taste keeps me from using it.

this helps but doesn't quite keep the lines from freezing in hard freezes. I bought them after reading the reviews and gave them a try-and they worked to about 28 degrees-but any colder and the line froze anyway. they do keep the snow and ice off the faucet handle and the Velcro works nice and it is easy to get on and off.

I guess I should've known better.  With the cold winter we've had and now a bit of a thaw here in nrn MD,  I am dismayed to see my pond losing water at an alarming rate.  I will now have to pull the whole thing out and redo the pond.  I will go with a 0.4 thickness this time around.

Hard to get a cup under ice shaved to fit..making it hard to use.

I really like the color and the design of this product.  I tried putting ice water in the morning and went out camping/hiking for the whole day.  Throughout the hike, the water was cold, which help a lot when you are hiking in a fairly warm day.  The only downside I found is that the plastic is hard to take off.

It takes a lot of effort to move the water up through the filter into the straw.  I wanted this for everyday use but its too difficult to drink from.  I will keep it for use when fresh water isn't available.

So far the machine has been making lots of ice. However, to install it required some contortions of the cord and some special metal duct tape I had in order to hold the wiring out of the way. I was surprised the tape stuck to the cold fridge box so well. In addition, the best choice of "funnel cup" that receives the water tends to ice up and water splashes out. None of the included funnels is an exact replacement for our old ice maker's. The shut-off sensor-system is different (horizontal blade versus wire loop) but seems to work.

it was a little hard to use because it would get cold quickly, after taking it out of the hot water, but I'm impressed by the strength of it after it cools down.

Purchased a while ago. Some of the pictures show a bit of an indentation around the edge, which might have held the water better if it existed. It was also difficult enough to fill that I ultimately stopped using it. With a bit of difficulty  it does make ice in a sphere, so 3 stars.

It's a nice concept but hard to work with the silicone to create an actual all round ice.  The silicone is too soft so the water comes out of the top too easily. Harder mold would have been better.
