Love these acrylic, BPA-free glasses. I just wish they had flat bottoms, rather than a slight circular indentation on the bottom. It's a drag pulling them out of the dishwasher so not to spill the water, drain over the sink (or dishwasher), and then dry the bottoms, and SIDES if you slop the water when handling/drying. That said, I bought 2 sets of 4, and use them throughout the week, and dishwash all on weekend. They all look like new and I've been using them for over a year. No scratches, no fog, no blemishes, none broken or cracked anywhere, and a larger version so I'm not refilling as often as I do with rocks size of this same brand. They have dimples where you can easily grip them around midsection, so they don't slide out of your hand, but also aren't flimsy or cheap looking, nor too heavy to lift. Funny thing: My friend did a double-take when he picked one up with sparking cider in it -- he thought they were broken, or from another planet (Haha!). They have other types of glassware (undimpled), but I can live with the bottom issue via dishwasher, and will I'll continue to purchase these glasses, as needed. I think they would be great for people with hand-grip issues. Enjoy!
