My order came promptly. It is exactly what it states.  The problem us that the float is to small and is easy to submerge without noticing defeating the purpose of the flag.  It gives almost no resistance when it is at the surface. So if there is any wave action you can not tell if it is at or below the surface. I will modify it with a bigger float.

The only problem I have with this Pump , the floater part is not going up or down when water levels change  therefore I had to use it as utility pump.

The end that is supposed to go in the solution floats, so it does not do as good of a job picking up solution.  I wish that it had a little weight on it.

Could be smaller, but it's pretty darn small as is. It's based on temperature differential. So to date, nobody else has come up with something this resistant to failure. It doesn't matter if there's buildup on the sensor, this is where conductive, optical, and float sensors fail. It also has no moving parts. It's also based on temp probes, which I don't think I've ever seen one fail. It can be adjusted as well to make a smaller difference in fluid level, you just turn the sensor to an angle where the probes are almost all straight into the water. And as far as your summer water being the same temp as air, I do believe it detects tenths of a degree, so unless the air temp was the same exact temp as the water, for a couple minutes with no change, then you might have an issue and it will start beeping. Otherwise I would think that scenario is a 1 in several thousand kind of probability. You would have other failures with other ato's before that would happen. I've had floats and opticals and problems with each.. I've had this setup for 6 months and there's all sorts of salt creep on it, and still haven't even touched it since I installed it. No need to clean it because grime doesn't affect it. I do wish it could reset itself after a high-level alarm, but I guess it's there for a reason. I was going to just program my Reef Angel to automatically turn the outlet on/off to reset it if that happened, but again, the alarm is there for a reason.

While this paddle float is made of quality material it's big enough to replace my PFD.
It also lacks any quick and easy way to keep it rolled up when not stowed away on my kayak bungees..

She doesn't use too big for my tank and the top part of the leaf floats to to of water so she can't swim over it and it prevents her from getting air when she goes to that side of the tank because it's on the surface

This float is good.  I had some issues keeping it aired up.  Not sure if there is a leak or not.  But it survived for the time in use.

This floating device is easy to blow up with a small electric air compressor and provides good support for your head when you are floating in the "belly up" position.  If you have great lungs, I suppose you could blow it up manually, but a small compressor would certainly be the easiest route. I bought one last year and it is now in its second season of service with no problems.  It even held its air during winter storage such that it only took a minute or so with the compressor to get it back to full inflation.  It's a great floating device for a pool or in a pond but I'm not sure you'd want to use it in the ocean where the water could be choppy.  It's hard to know if it truly enhances your tanning, but it's a comfortable way to relax and float around on when it's pool time. I certainly wouldn't hesitate to buy it again should the need ever arise.

OK So I love these floats. They are comfortable and easy. I love how you can float and be in the water at the same time. Very comfortable. The only downfall I can see so far is that the sides and the pillow you blow up...easy peesy....the problem is I either have to leave it in the pool or take the air out to fold it up. It barely folds into circle for storage with air in it. Because I have a puppy that chews, just pulling it out of the water and leaving it by pool is not an option. Blowing it up everyday is also not an option LOL sooooo I leave it in pool for now. It has not seen any damage yet. Other than my personal little issue......the float is wonderful!

This toy is nice in looks and great for kids but it floats on the side.. I hate that plus how does the water gets filled.. its fustrating...

I've realized that the flakes are not good for a small tank. Pellets are easier to clean and do not pollute the water as much.

This float will not fit two people, its barely fits one grown person.  Even though it has two cupholders, you can't really use them because you are sitting on top of them.  Used it once in the lake and it deflated and filled with water.  When I inspected it the next day there were two holes in the bottom.

Blows up fine and stays inflated but in not very buoyant - most likely because the bladders are a little too small, this leaves you floating in the water more than atop it.

Good Build and floats well. a pity the bottom cannot be opened to allow us to put small items such as keys and money inside.

It is very small and doesn't make much of an impact.  It kept falling off the barrel edge I put it on (as shown in the picture) into the water. I sent it back.

Nice inexpensive float, good size and made of durable material. The water bag portion is nice but i use a weight to help keep it upright since i added a flag stiffener of wire that makes it want to lean over. The weight dangling from the bottom anchor loop solves this.

It's rather small. I would think one might need something with a better grip if a car goes underwater. I'd look for something else.
