Got a good deal on connectors

I was looking for some Heat Shrink Butt Connectors and saw SolderStick had a multi-pack savings offer. I ended up getting a larger pack than I originally planned because the per-unit cost was so much better. The shipping was free too, which was a nice bonus since my order was over the threshold. It felt like a solid purchase and I saved a decent amount compared to buying smaller packs elsewhere. They arrived pretty quick, about 4 days to get to me in Arizona.

So happy with these connectors!

I ordered a bunch of the Red Solder Connectors and some Heat Shrink Tubing for a project I've been putting off. I usually hate electrical work, but these SolderStick connectors made it genuinely easy. I didn't even need to use my clunky soldering iron, just a heat gun. The connections feel super strong and look really clean, plus they're waterproof. I'm definitely going to recommend these to my buddies, especially the ones who hate soldering as much as I do. What a relief!

Detailed thoughts on my SolderStick order

I recently ordered the SolderStick Waterproof Solder Wire Connector Kit along with a Wire Stripping Tool. The ordering process on the website was straightforward, and I received an email confirmation right away. My package took about 6 business days to arrive in upstate New York, which was within the estimated delivery window. The kit itself was well-organized, with different sizes of Solder Seal Wire Connectors clearly separated. I used them on some outdoor lighting, and the connections felt very secure after applying heat. I already owned a heat gun, so I didn't need to purchase one from them. The wire stripping tool worked as expected, nothing fancy but effective. I haven't needed customer support, so I can't comment on that aspect. Overall, I found the product quality to be good and the items performed as advertised. It's a convenient solution for waterproof electrical work.

Good kit for quick fixes

I got the SolderStick Waterproof Solder Wire Connector Kit a few weeks ago for a small wiring job on my boat. It worked out pretty well. I didn't need my soldering iron, which was nice. Everything went together easily. I would buy it again for sure.

hey, anyone used these solderstick things for marine stuff? worried about salt water.

E Emma D. 1 month ago

Yeah, I used them on my boat's bilge pump wiring last season. Held up perfectly through all the chop and spray. Pretty solid.

G Gwen 1 month ago

From what I remember seeing on their site, they are actually made for marine use. Should be fine.

Is Solderstick better than just using regular crimp connectors? Been debating which to get.

J June V. 1 month ago

I think so, especially if you want a waterproof seal. Crimp connectors can pull out if not done perfectly, and aren't usually sealed against moisture. The solder and shrink tube on these make a much more secure and sealed connection.

D Dana 1 month ago

For anything exposed to the elements or vibration, Solderstick is probably the way to go. Crimp is okay for interior stuff but these are definitely more robust and permanent.

Do I actually need a fancy heat gun for these or can I just use my old basic one?

C Carly Whitfield 2 months ago

Nah, you don't need anything special. Just a regular heat gun that gets hot enough to melt the solder and shrink the tubing. I use a cheap one from Harbor Freight.

C Colin 2 months ago

They sell one on their site, but it's not like you HAVE to use theirs. Any heat gun that can do the job is fine. Just avoid lighters, heard that's a no-go.

how long does shipping usually take to, say, LA?

C Cody Doyle 2 months ago

From my experience, usually about 3-5 business days. Depends on when you order, obviously.

K Kate G. 2 months ago

Mine took about 4 days to get to me in San Diego, so LA should be similar. Pretty standard shipping times, nothing crazy fast but not slow either.

Are these Solderstick connectors actually permanent? Like, if I use them on something important, will they hold up forever?

S Sam R. 2 months ago

Yep, they're designed for permanent connections. Once that solder melts and the heat shrink seals, it's pretty much locked in. I've had some in my car's audio system for years without issues.

J Julia N. 2 months ago

They're considered permanent, insulated, and waterproof. As long as you apply the heat correctly, they should last a long time.

Thinking of grabbing a big kit, do they usually have any sales around now or should I wait for like, black friday?

S Shane Romero 2 months ago

They do holiday sales, so Black Friday is a good bet for deeper discounts. But sometimes they have smaller seasonal promos too.

M Mike 2 months ago

I saw a bundle deal a few weeks ago for like 15% off a bigger kit. Might be worth checking their site or signing up for emails.
