Bests & Worsts Reviews from Amazon

What can I say? I've owned many water bottles before and it was only by accident that I ran into the Fashy-brand bottles on Amazon; I am forever glad that I did. After using this bottle for 2 years, it is hands down the best one I've ever used. ######### AFTER 4 YEARS ###### (1) YELLOWING - I have two of these Fashy transparent bottles and still love them to death (so does my mum), but one thing to note that I also experiencing a "yellowing" of the bottles. It is NOT based on the water supply. I have learned these bottles are made of TPU (Thermoplastic polyurethane). 'Transparent' TPU discolors and turns yellowish (same as my iPad case). Anyways, it doesn't affect the performance, but I loved the original clear, clean look. It still has it, but with a tinted yellow discoloration. The manufacturer should use aliphatic TPU based on aliphatic isocyanates to prevent the yellowing. (2) Also, the smooth side of the hot water bottle has begun to peel somewhat. It has not affected the job performance. I tend to abuse my bottles (lie down on them -- all 165lbs of me) and put boiling water, so YMMV. (3) Bottle leaks if I don't tighten it very hard after years of use/abuse(?) PROS: 1) Huge mouth and anti-"spurt" lip prevent water spitting back out like those old rubber ones 2) OMG It's transparent!!! No more guesswork about how much hot water is inside! 3) VERY easy to tighten, and SECURE bottle cap! I've literally sit on this thing with boiling water, and filled to the max, and it has never leaked 4) Leakproof design, unlike old rubber counterparts, due to the fact that is made in a single mold, without any kind of 5) It's frikken' transparent!! CONS: 1) No doubt about it. For $24-27 shipped, it is expensive, but IMO if you use this thing daily like I do for muscle pain/helping with sleep/feel warm and toasty in a cold room, then it's damn worth it (this is coming from a loyal tightwad gazetter :P) 2) Yellowing of the bottle 3) Long time, top portion, smooth side of the bottle begins to peel after 2-3 years. 4 years later, still working 4) LEAKS after 3-4 years. Make sure you tighten the twister HARD after years of usage! Still the best hot water bottle made. NEUTRAL: 1) Sweet lemony smell for the first few weeks, then disappears
