Not the easiest to fill
355954
As others have stated, filling the tray with water isn't that easy. It took me a few tries. I should've paid more attention to the sizing because the ice balls are smaller than I'd like.

i like the kettle  - it heats up well and pours easily .  The only draw back with this product is that it is not that easy to fill ..
the lid opens well enought but  not all the way and as a result i find i need to wrestle a bit with the faucet to get it filled up.
apart from that slight inconvenience, it is good value and looks very nice as well

It's difficult to know where to fill these up with water, and I either get over-filled molds or under filled. The design is fun, but it is difficult to remove the ice once frozen.

Well made materials, fit and finish wise, but hard to fill and clean.  Sent it back.

I love the idea of the trays but they are hard to fill in order to get a perfect cylinder. I tendon't to get half a cylinder. They alsolet really fast but that has nothing to with the tray though.

They are not as easy to pt on the pail as I thought they would be.  Also, there is always an off amount of waste left at the end. They are easy to use with their cut and tie system. A bit pricey.

hard to fill up water ( you actually have to fill up each sockets where the regular plastic trays are fill up by over flowing any of sockets.
this one, the top is almost flat so if your water over flows it does not guided to the other socket but goes randomly.

also ice expands towards each other and the rubber gets pressed between them so that pressure makes it hard to pop out the ice cube.
you actually have to squeeze out the ice or push real hard.

slight disappointing design .

Handy, but it doesn't light very easy. Once lit it works good. Also the refill process it leaky and messy

I like the item but have found it a bit hard to use and it doesn't spiralize all the items advertised very well.

I really enjoy not having to fill the dog's water bowl four times a day (2 Golden's and a Border Collie) but there are a few limitations with this product.

1)Filling it isn't easy if you don't have a deep basin (like a janitorial basin in a basement or the like)
2)Cleaning the inside of the water jug to get rid of the inevitable algae buildup takes some creativity and effort.
3)It isn't easy to keep the watering portion of the bowl clean since it doesn't need to be filled as often as a regular watering bowl.

This is my second one (first one finally cracked from overuse as a stool when I was too lazy to sit in a real chair to put on my boots). I thought in the time between my first purchase and this one (eight years) they would find a better solution for the five gallon bottle. Filling it is difficult. It does not fit in any sink I have in my cabin so I have to either fill it outside with a hose (Pacific Northwest damp, rain, cold = not fun) or in the shower.  Filling it in the shower is a pain and can be messy putting it back in place ( I have one arm that I can't lift with.. comical but not fun).

The water drains out all at once and I have to clean the mud out of it each time I refill it. It isn't really hard to refill but it's not exactly easy either. I've gone back to watering my ivy from a measuring cup.

Rather difficult to fill. You have to hold the product up while filling, so water does not spill out. There seems to be only 2 clear plastic outlets for water to come out, at the bottom ( face facing soil ). Seller, Sprinklersupplystore, is excellent. Highly recommend seller.

I love these ice cube forms, but it's a bit tricky to fill them and to pop out the cubes.

It takes a lot to blow these things up! There are 4 sections that need to be blown up. We did not have a pump so we had to blow them up by mouth. Once you start, it is not easy to get all sections filled and a few of the holes were so tight it was hard to get air in. Other than that, they were cute and made the table look very festive. They were a little small and one you put ice in, there isn't much room for anything else.

My wife and I got tired of refilling our dogs' water dish time and time again and hope this would stop that which it did. Though as a note to other buyers the opening to fill the reservoir is actually at the bottom which is annoying. I would have preferred to have the top be the filling point.

The square cubes are great. However the circular cubes are very difficult to fill. The top lid does not seal/snap/click in place assuring minimal water leakage therefore not all the circles are complete.
