Good value and priced okay

Great works perfectly

Why did I wait so long before I started using these things?

Good quality. Product as described.

These are perfect for what I do (security alarm and CCTV technician) I use them for low voltage wiring almost daily. You cannot beat the price and I would not recommend any other brand. Dolphins (blue or white) are fantastic and just work. I prefer the blue ones as they have a gel sealant inside the connector (vs the white, which do not) so that water and whatnot has a harder time penetrating the splices. Easy to un-crimp too and usually holds together just fine if you need to reuse after fixing a splice. Love em. I will only use dolphin connectors.

The product received was not the same as what is advertised in the photo. 34;Dolphin34; is not printed on the connector, but they appear identical. I can't comment on how the performance differences from the name brand, and they may in fact be the same connector just without the branding for a better price.

These totally rock for splicing together RGB LED lights, 18-20 AWG ... esp. when in a hurry and without any solder or shrinkwrap. I used these and regular pliers (the jagged jaw part) to crimp. I seem to have better luck removing tghe shileding and twisting together, then clamp one of these on. THen finish it up with electrical tape or the liquid electrical tape. Fast and easy for field repairs on LED(s) in the field, in my case for a Christmas Lights display.

As advertised

Great product

Good old B connectors. Chicklets, beans, whatever you call them. They've been around for decades and keep many phones ringing and door contacts working. The old telco guys will tell you these spell trouble, but you won't have a problem if they're used correctly. The gel sealant is a type of dielectric grease. It is intended to, with the help of the wire insulation that is supposed to still be on the wire, keep the metal-to-metal connection airtight to prevent oxidation and corrosion. It is not intended to keep the splice waterproof. If your splices will be in direct exposure to water, these won't last. I also wouldn't use these for transformer power, sirens, or anything that draws any current higher than a keypad. Excellent connector for telephone and alarm sensor loop wiring. These are really only meant for wire gauges from 22 to 26 gauge. You won't have a good reliable splice at larger 18 or higher wire. Unlike the UR and UY 34;Scotchlok34; type connectors used by the telco guys that can only use solid wire, these can be used with both solid and stranded wire. They're also excellent for connecting a 22g wire to a resistor lead in a security system. Make your connection the right way and you will never have a problem: Insert both wires into the connector until they're in completely. Don't push them in so that one is on top of the other. Just side by side. Then press the connector flat. Long-nose pliers without a cutter, linemans pliers, any tool that presses flat will work fine. I have a pair of 634; side cutters that have a point behind the pivot that works great. One squeeze is all you should need. The teeth in the connector will bite through the wire insulation. You can tell you have a good connection by trying to twist the connector around on the splice. It shouldn't move around much. I've used thousands of these to connect telephone lines and alarm system devices with no issues. For very damp basements, the gel model is a must have. I've seen the 34;dry34; kind completely corrode and disintegrate in some New Jersey crawl spaces under houses near the shore. I've seen techs use these to connect 18gauge wire and it was always a nightmare to come back and troubleshoot loose connections. Do it right and you'll never have an issue.

great price - great seller - Dolphin brand are the only connectors we use - do not buy offshore ones - these are the best.

an amaizing Product and love that customer service. Thank you

Quick and easy

ok

Both ends of these crimping type connectors are open, but only the end the wire goes through has sealant. So water can get in to the wires from the other end. Kinda makes the idea of having any sealant silly. These are like a conductive inside out metal cheese graters that you place your wires in then crush the sides together trapping the wires and making an electrical connection. good for small wires, unexposed to the elements.
