Cute, reasonably priced and useful!
I purchased 3 sets of the pink hand warmers: one for myself and 2 as gifts. I purchased one for myself in hopes of helping to ward off painful Reynaud's spasms in the cold weather and I do think they have made a difference. I put one in each coat pocket when I'm going to the grocery or will be out and about in the cold. If my hands start to react, I just push the button and have instant warmth to keep a Reynaud's reaction at bay. I think they will be useful year round as air conditioning in the summer also causes painful spasms. Once you become familiar with how they work, there is no need to even take them out your coat pocket to turn them on or choose the setting. When you turn them on, they warm up immediately and do get very warm on the highest setting. They are cute, small and unobtrusive in my pockets. While I haven't timed it exactly, the battery seems to last about 6 hours, more than enough for my purposes. So far, I have had no problems with my set and reviews from the two gift recipients have been positive. Should that change, I will update this review.

Fast charging!
These are great! They charge fast and last for a while. They have three different warmth settings and get pretty warm on the highest setting! They are perfect for pockets, inside gloves, just in your palm - easy to use. My fingers are always cold in the winter, and they work very well. They are cute too and the color is pretty!

Warm - Nicely Packaged for Gifts - Lots of Color Choices
Purchased a set for my daughter & granddaughter as gifts. Both love them, granddaughter walks about 20K steps a day as a college freshman on campus. Daughter works at same campus, so there's a hike from parking & sometimes to in-person meetings. Both say they work well. I just bought a set for a friend who is also freezing. Haven't given to her yet. Bought one for other granddaughter (also a FR on same campus walking 20,K steps), but it has a design. Same company, but there's another option to review that one. She loves hers also.

A Stylish and Effective Solution for Cold Hands
As someone who often struggles with cold hands during the winter months, I was on the lookout for a reliable hand warmer. The OCOOPA Rechargeable Hand Warmers have exceeded my expectations in every way.These hand warmers heat up quickly and offer multiple heat settings, allowing me to adjust the warmth to my preference, but I tend to always have it at its highest. Whether I'm on my morning jog in the early morning chill or attending an outdoor event, they provide consistent and comforting heat. The battery life is moderate, but does tend to need charging after so long, but luckily they recharge quickly via USB-C.These are a must-have for anyone seeking a stylish, efficient, and versatile solution to cold hands.

Work great!
I got these for my husband because he's a teacher and has to stand outside at the school for drop-off and pick-up, etc. and it's super cold and snowy in the winter where we live. He says that they work great and keep his hands warm while he's outside. They were also super easy to charge up. We love how they are reusable and you can turn them on and off instead of spending money on disposable ones that can't be turned off or re-used. They heat up very fast, like instantly, so you're not sitting there waiting for them to warm up. We are vary pleased and would definitely recommend!

Colors are not listed on boxes
I bought four sets of these, one for myself and three as gifts. They’re great and I look forward to using mine, but the only way I knew which one was mine was because the package arrived separately and I knew which color was delivered. The boxes are identical with only bar code stickers with an alphanumeric code on them as any differentiation between them. When I asked the question here on this listing, the response was, "Dear customer, Our packaging is grey by default. If you need to distinguish the color for a gift, you can contact our customer service to verify the color. Best regards," - so I’ve filled out the form on the website and now I wait. I’m glad I didn’t wait closer to Christmas to buy them, and want others to be aware if they order multiple colors as gifts. (Why wouldn’t the stickers just list the color??)Response from CS:Dear Customer,X004BF3O1X is the hand warmer UT3041 - black base + green casing, and X004E43AAV is the hand warmer UT3041 - black base + red casing. We are sorry for the confusion.I’m still giving 5 stars because the product itself is great: very warm, heats up quickly, a cute design, and an easily portable size.
