From the time I discovered S’well about a year ag I’ve be entranced by them; their design, colors, patterns, and styles for drinking. The design captured me because they were easier for me to hold due to my tremors. I’d given up glassware and was using stainless steel with silicone wraps to prevent dropping. I loved having triple insulation and my bedside water being cold for 2 days...until my 3 mo. old puppy knocked a s’well traveler over and it was never the same. There were no outer cracks and no inner breaks or rattles. But somewhere there’s damage. It’s happened 3 more times since then with the same results. I still like s’well as long as they’re in new condition. Just BEWARE of the drops. Hence, the 4 stars.
