Customer Reviews
Great value on kit
This was my first time buying from Solderstick. I picked up the Electrical Wire Splice Kit during their seasonal promotion. The discount made it a really good deal, especially considering the quality of the heat shrink tubing and connectors. I usually shop around a lot for the best price, and this felt like a solid purchase. Definitely got my money's worth and the connections are holding up well.
So happy with these!
I absolutely love these Solder Seal Wire Connectors! They made my automotive project so much easier. The connections feel super secure and the waterproof feature is great for under the hood. I'm definitely telling all my DIY friends about Solderstick. I'll be back for more soon!
Good connectors, quick delivery
Bought the SolderStick Waterproof Solder Wire Connector Kit. Worked as advertised. Shipping was fast, got it in about 4 days. No issues. Will buy again when I need more.
Solid connectors, heat gun so-so
I ordered the SolderStick Waterproof Solder Wire Connector Kit along with their Heat Gun for Soldering. The connectors themselves are excellent; they sealed perfectly and seem really durable, exactly what I needed for some outdoor wiring. Delivery took about 6 days to reach me in Arizona, which was reasonable. The heat gun, however, felt a bit flimsy compared to others I've used. It got the job done, but I probably wouldn't buy it again separately. Customer support was helpful when I had a question about wire gauges before ordering, so that was a plus. Overall, good experience for the connectors.

Share tips, ask questions & help fellow shoppers save more
What's the deal with returns if these don't work out? Is it a hassle to send them back?
How do these compare to something like Kuject or Wirefy? Are they basically the same thing or is there a difference in quality?
I'm a new customer, is there any kind of discount for a first order? Or like a free shipping code I can use?
Do I need to check wire gauge carefully, or are these pretty forgiving for different sizes?
Are these connectors actually permanent? Like, will they hold up long term or will I have to redo connections down the road?
