Customer Reviews
Good quality and free shipping!
Has anyone else found the Heat Shrink Tubing from SolderStick to be really good quality? I was updating some wiring in my car and needed a decent variety pack. Their prices were competitive, and I managed to snag free shipping, which is always a plus. I also looked at their Solder Seal Wire Connectors but didn't need them this time around. My order arrived pretty quickly, within about 4 days. The only thing I'd mention is that I wish they offered more specific sizes of tubing rather than just variety packs, but overall, a solid experience.
Great value, but a quick question!
Hey everyone, has anyone used these SolderStick kits for marine applications? I grabbed the Electrical Wire Splice Kit and found it worked perfectly, and free shipping over $25 was nice! 🚢
Connectors work well, good support
I ordered a set of the Solder Seal Wire Connectors and some Heat Shrink Tubing for a wiring repair on my truck. The ordering process was straightforward on their website. It shipped out pretty quick and took 5 days to reach Denver. I had a question about wire gauge compatibility, so I used their online chat. Support was helpful and answered my question right away. The connectors themselves worked as advertised. I used my own heat gun and they sealed up nicely, making a solid, insulated connection. The wires felt really secure. They seem pretty durable; I think they will hold up well. Overall, a good experience.
Good kit for the price
I was looking for some waterproof connectors for a boat project and found SolderStick. I picked up the SolderStick Waterproof Solder Wire Connector Kit. Got it during a multi-pack savings deal, which brought the cost down. Shipping was free too since my order was big enough. It felt like a pretty good deal overall for what I got.
Quick delivery, easy to use
Needed some Red Solder Connectors fast. Ordered them and they arrived in 4 days. Used them with my heat gun; they worked perfectly. No issues at all. Made the electrical connection simple and quick.

does Solderstick offer free shipping? or do I need to hit a certain order total?
are these things really waterproof enough for boat wiring? like, marine grade waterproof?
Hey, wondering how long shipping usually takes for these kits to like, California? Need some for a project next weekend.
can I use any old heat gun for these or do I need a special one?
how does the return policy work if I get the wrong size or something?
