Review on 🍷 HaloVino Reusable Plastic Stemless Wine Glasses - Dishwasher Safe, Stackable, Shatterproof, and Unbreakable - Recyclable, Not Disposable - Ideal for Outdoor Parties and Receptions - 12 oz (Camping, Pack of 6) by Elliotte Rogers

Great idea, love the way they fold. The top edge is a bit sharp. Not so much that I cut myself (at least not), but enough that I don't feel good on my lips. For a design aimed at enhancing your wine drinking experience, they're good for the nose but bad for the mouth. I've found that I don't use them for this reason. UPDATE: Apparently others have expressed the same concerns. The inventor and CEO of HaloVino sent me a set of his new glasses to try out. The top half has been redesigned with a slightly different shape and smoother edge. I used one last night and found it significantly better. I suspect I'll be using them a lot more often now. It's also great to see that the company is listening to their customers' concerns and standing by their product. I have raised my rating from 3 stars to 4. I would give 4.5 if I could get half a star.
