I have Raynaud's (cold finers/hands), and I received a pair of these as a gift over the holidays. I ended up liking them so much that I purchased a second pair. I normally wear a size small or extra small in gloves, and the size XS/S fits fairly well (they're a little on the roomy side, but not by a lot). There is a hook and loop (velcro) closure on the underside of the wrist to put the battery in while it's connected to the gloves. This took me a little while to get used to, but I mostly stopped noticing it after wearing the gloves a few times. I did find that on this version of the glove liners (with a velcro-type wrist closure) I could sort of tuck the battery on the back of my wrist under the velcro flap so that the velcro goes over it when securing the gloves over my wrist. In that way, the battery feels a little more like a watch or a similar wrist device, which feels a bit more natural to me. However, it can take a minute to secure the battery that way, as it's not designed to sit there, and there would be a bit of a risk of the battery falling out (and potentially getting lost) if you're outside and/or doing a lot of physical activity.I love that the heat is mainly directed around the fingers and a little bit on the back of the hand. That is perfect for Raynaud's. I cannot feel any wires at all in these gloves (they just feel like normal gloves, other than the fact that you can feel heat from them and the fact that the battery is sitting at your wrist). These are glove liners rather than regular, insulated gloves, so they can be worn inside another, larger pair of mittens or gloves, but I mainly use them at home or in other environments where it's not too cold. They are touchscreen-friendly, so I can use my phone while wearing them, which is a huge help. They are a little bit too bulky for me to be able to type on a regular keyboard efficiently, so unfortunately I don't usually wear them while typing (unless I'm willing to type slowly and use the delete key a lot).Overall, I'd definitely recommend these to other Raynaud's sufferers for everyday use around the house, office, and other indoor uses (or outside if it's not very cold out). They are pricey, but I feel they are worth the money. You may be able to wait for a sale, a coupon, or an Amazon Warehouse deal on these if the price is too high for you normally. I've since tried a couple of other Savior Heat products (regular heated gloves and heated socks), and those have been working well too, so I'd recommend this brand in general.
