I have other acrylic glasses that I purchased from a grocery store that eventually cracked/leaked at the bottom and never was as new or clean looking as when first purchased. These Bravario rocks/whiskey glasses look great! They are not as wide for my hand to hold as the others which is a bonus, but they still hold about the same amount. I like the solid bottoms; the old glasses bought elsewhere had finger indentations on the bottom, which may have added to the cracking/leaking issues. I'm very satisfied with these unbreakable glasses, and will probably add to my collection now that I know these work so well. Plus side: If I drop them on a kitchen tile floor, they won't explode into hundreds of glass chards and slivers. These glasses are top-rack dishwasher safe, BPA safe, and also do not contain lead nor additional weight as my Longchamps leaded glasses do. As you age, you realize lighter weight things are the ticket. These are really no-fuss options to glass. Hope you enjoy product as much as I do.
