I was in need of a new thermal shaker bottle as my first generation Radian bottle was losing its insulation, and the top cap is collecting gunk even after thorough washes. This bottle not only captured what I love about the Mandalorian's suit, where it is brushed metal with a modest contrast (my Radian bottle was also the brushed metal variant); but the Mando' print and associated Star Wars logos feels premium, where it will remain there even after regular washes. You can FEEL the print, and it isn't like a simple decal/temporary tattoo kind. The Body Bottles are wider in dimension compared to the traditional YUYU Bottle, measuring 75cm x 12.5cm, giving you that extra surface area coverage to target heat on those painful spots. The first to introduce a wearable hot water bottle, the strap feature on the covers of the Body Bottle gives you the ability to tie your BBs around your shoulders or abdomen, helping to gently ease any aches or pains while allowing you to carry the warmth and freeing up your hands all at the same time. As for the main features of the bottle, the new spout cap is a great upgrade from the Radian, as the rubber gasket is removable - making it easier to remove stain collected below it. The main cap's gasket is also improved, where there are no ridges anymore, but a smooth surface, making it less likely to hold onto stains/gunk - easier to wash! Lastly, the rounded bottom of the bottle does indeed make the shakes I make mix better. No residue collected below, and less things to scrub. Lastly, which isn't a promoted feature, the opening of the bottle is slightly larger, making my whole hand easily fit inside and reach the bottom of the inner side - again, making it easier to wash.
