Transparent Classic Hot Water Bottle - Made in Germany (New Model)

The divots help the bottle keep its shape. You must follow instructions to pour hot water no more than 80 degrees centigrade very slowly and carefully. Fully empty and hang to dry in a low humidity area. I also encourage you to use a bottle cover to prevent contact burns, which is a risk with any hot object in contact with bare skin. You also need to squeeze out excess air once filled. Unlike rubber bottles, the thermoplastic won’t suddenly explode on you and the chances of hot water suddenly bubbling back up are small (it’s only bubbled back up on me once, when I wasn’t paying attention). I know fashy makes a bottle stand to prevent accidentally burning yourself while filling up, so I recommend using it if you have poor coordination or distractions in the form of small children and pets.

Outstanding product. First one lasted 12 years! The new design is really in testing and helps transmit heat

The plastic is turning yellow and looks gross after less than two month. I’d like to purchase a sleeve but can’t find one. Be mindful of color changes

Love a hot water bottle and FASHY is the best out there. Typical German made product - with pride and quality!!! I love this brand so much that I am buying more as gifts, it's low tech, you don't have to be in pain to use one (my body runs a bit cold), and well made.

I bought this to replace the Fashy hot water bottle--the traditional style of hot water bottle--I bought about five years ago. The circles aren't designs on the surface of the water bottle but rather baffles between the two sides. This reduces the amount of water the bottle holds, which means it doesn't seem to hold heat for as long as the traditional style does. The baffles also make the bottle feel stiff, so it's not as satisfying to hug to one's chest. I like Fashy's hot water bottles in general--they're sturdy, well made, and their transparency makes it easy to see when to stop pouring water into them--but I prefer Fashy's traditional style over its one with the baffles inside.

With this model's multi-chamber design you get about an hour, at most, of heat retention. My advice is to go with Fashy's old version (https://www.amazon.com/dp/B00WJPT46K?ref=ppx_yo2ov_dt_b_fed_asin_title), which is phenomenal.

Very good

I prefer the older model. This one was a waste of money and i can't return it! It doesn't get warm like Flashy's older model.
