Review: LOVE these things! I should buy Fomentek stock! - I'll be candid...when I pulled them out of the box I thought they were pretty low-tech for the price and I thought I might have gotten ripped off. But I tried them and, boy, are they nice!! Instructions say a third full of hot tap water and they're floppy enough to envelop your neck or other hard-to-cover spots. I fill them and put it in a flannel pillowcase, making it easier to slide it down my back (holding onto the pillowcase opening for leverage) to get my traps and between my shoulders (hurty spots). It's also nicer on the skin that way when the bag is extra hot. As the bag starts to cool down, you can either take it out and use it bare (another half life) or put your feet on it within the pillowcase--cozy! I can do this a couple of times for a night of TV-watching. It's comforting to put on my lap while also warming my hands on top (I imagine you could do a hand-softening treatment if you have disposable gloves over oil or paraffin soaked hands--note to self, must try...). I will also tuck it between the sheets before bedtime when it's cold (I don't like electric blankets). I've also used it to keep stones warm when I give him a nice hot stone massage (he LOVES it!). I imagine it works well for warming up other non-body things too. You can calibrate the heat for whatever your use easily from your faucet. The plugs are really good! Pop off when you want them to, but secure (I've gone to bed with these warming my neck). I've used these easily a couple hundred times from Dec through Feb, daily, several times a day, when it was cold. Probably could have made my own towel warmer too with both sandwiching towel in a basket or container. I plan on putting chilled water in and putting under my pillow when the hot, humid months begin. I also plan on packing these on trips to ease travel-related discomforts. These are easy, portable (packs down like a Ziploc), durable (I've even put more water in than recommended for longer heat retention, but then it's firmer/less pliable), multi-purpose with no failures nor sign of impending failure, great heat retention, no electricity needed. I've used them on my shoulders while driving to the chiropractor to help warm up/relax the muscles before a treatment. Better than a hot water bottle, now I'm thrilled with Fomentek's simple design and all the things I use them for. What a 180! By the way, I bought the large one too, but these small ones are the ones I grab, often two at a time, feet and hands, neck and tummy, tummy and feet...
Review: A must have for aches and pains - Excellent bags for pain relief. Love the immediacy of heat. I especially use the smaller bag. I have been using these bags for years. But the large size is excellent to lay on. Very well made. Never had an issue with leakage with the top but over many, many use, there will be water pulling between the layers, which means it’s time for a replacement. Way more helpful than a traditional hot water bottle for my needs.

### ⭐⭐⭐⭐⭐ Perfect!!! Just Not Too Hot of Water,
*by I***O on December 28, 2021*

So follow the instructions for sure on not putting water in it that is too hot. Eventually your bags will leak if you continue to put water that is too warm in it and definitely do not put in boiling water. I am a massage therapist so I use these for clients. With all the concern with electrical heat our household uses these as bed warmers and as a therapist I especially like that they mold to your body. Neck, back, etc. Clearly you don’t want to put them under your body as they may rupture. The five gallon bag is quite large so be aware of that. If you laid it on your chest for most people it would go from your clavicle to about the top of your thigh. I recommend these to every single one of my clients and will always be a forever fan. Smaller bags are great for making your own ice packs or use them warm for small area pain. I think the middle of the sizes is the best as the 5 gallon will be too large for most.
