Review: I've been using these for a few years with Christmas lightning (outside & in the snow). These work really well and are much more convenient and easy to work with over traditional soldering and shrink wrap. I will say that I have noticed they do seem to have an unused shelf life. I've found that some of the unused sleeves, if I try to use them a year later, the solder won't melt. That's not a huge issue as I typically just buy up several prior to the season and they work well.
Review: Great product

### ⭐⭐⭐⭐⭐ Review
*by P***E on 31 January 2021*

I was looking for some wire-to-wire connectors, which these do just fine for, but I actually found them to be very useful for RGB LED (4-pin 5mm) bulbs. Bezels for these bulbs will come with 2-leg mounts, so you're really left on your own if you want an RGB LED in a bezel mount. Anyway, these solder seals are perfect for them - the legs extend out past beyond the center soldering point, which makes things very easy. I'm using the 22-18ga seals, and while they grip well enough for a solid, professional looking connection, you may want to use the smaller size if you intend on doing pin-pin / pin-wire connections.
