Worked okay but I didn't check my lights and the box didn't say. Turns out mine is probably closer to 8mm wide. I had to bend the terminals on the outside in and do a LOT of fiddling but the product worked well and held it tight.The issue was only me not knowing the size. If I bought a 10mm light string in sure it would be really easy plug and play.Thankfully it didn't break when bending the small metal contacts. I had to open it a few times to adjust and the plastic clip holding it closed didn't break surprisingly.The plastic guitar pick looking thing was useless but a pocket knife blade or glasses size flat head screwdriver will work well.Saved me from needing to buy another light string after stapling through the cable.

These things are awesome! My kid’s ceiling is 52 feet. *Thought* it was 48ft. So I Bought 50 ft of LED. It came in two 25.something ft strips(10mm)... Plus they had a few extra inches on each set, so I figured it would be perfect and I could just cut off any excess.The plug allows both sets to connect to the same power supply. You hang them in opposite directions and pray they come together.Hid the plug nicely behind the door. Hung the first strip and quickly realized my measurements were wrong because it definitely did not cover half of the room. LolRe-measured and realized I was actually going to need to use these little connectors, and also use a little bit off of my small set of 16ft of LED lights. They are 8mm though. 🤔Cutting off the prongs to the second set of 25ft strip to connect this was nerve-wracking. I needed to cut it off so the second strip of lights wouldn’t be upside down at the connector. Connector worked! I had already hung the first strip so the adhesive paper was already removed. Took several minutes to get the end under the prongs. I had to use the end of a pushpin to ever-so-slightly lift the metal plates in order to slide the strip underneath. I then used the point of the tack to push them back down. That was a pain up at the ceiling, but doable.The other side still had the paper backing and took 4 seconds to connect. (Once they are connected just lift away the paper backing from the second set and cut through with scissors so you can continue to peel and stick in increments as usual.)Also note: the lights on the second set were possessed and not matching *until* they were straightened out back into a straight line. It seemed like the connection was bad and only worked if I squeezed the connector tighter, so I was getting nervous. I kept making sure the metal clasp were pushed down onto the copper, but as soon as I released the pressure, it would stop working correctly. Tried just holding it up straight where it would be hung and Wa-la! The second set up the color synchronized with the first strip. It just needed to be in a straight line to fix itself.Finished hanging the second set and sure enough I was 2 feet short.I could’ve just hung the 3rd smaller set of 8mm lights into the units power supply since the second connector was still free(it worked, I checked) and then cut off the rest, but then that set wouldn’t have the power supply prongs any longer.I didn’t want to ruin that, so again I used another connector and just cut a couple of feet off the end of the 3rd set. Even though I used this to connect a 10mm set to the 8mm set, it still worked flawlessly.Now I still have an extra strip of 14ft of LED lights intact and the power supply to go with it to use elsewhere. Also note: I didn’t have to scratch off the ends of the strips before sliding it into this connecter because my strip connections were already copper. Apparently some sets are covered with silver that need to be scraped off to reveal the copper.These connectors are basically mandatory! There’s no way I was going to have power supply boxes and extension cords hanging down every 16 or even 25 feet. So ugly. Also necessary unless I wanted one of the two sets from the 50ft box to be upside down. It’s just the way they are made. Not sure why they don’t offer lights with the prongs on the opposite end of one set since they have to start at the same power point and be hung in opposite directions but these connectors saved the day!Would recommend and buy again.

Works well, being half assembled out of the package was helpful. Wish they came with adhesive backing.

Work very well, adhesive quality is very important,

These connectors are difficult to pry open and the pick that comes with it is useless. I was able to open them using a micro screwdriver but even with that it was tricky to open without breaking the tab that holds the connectors closed. Once they're opened inserting the LED wire is tricky as well so my advice is to have the LED lights turned on when connecting the wire to the connector as you're likely to find that they're not working after you close the connectors. Having the LED lights turned ON will allow you to see if you have a good connection. Don't worry these are low voltage. The instruction is not very useful so here are the steps I took to connect the wires:1. Once the connectors are opened, the trick is to lift the 4 metal silver wires inside the connector so that the LED wire strip can be tucked under them to have tight connections. I used a flat micro screwdriver to lift the metal wires but do it gently to prevent breaking them.2. Tuck the LED wire underneath the 4 wires inside the connector and then close the connector tab. There's a channel in the connector where you can slide the LED wire.3. Shut the connector tightly and make sure the tab on the connector snaps closed. This step will push the lifted metal wires down for tight connection.4. Do the same to the other end of the connector with the LED wire strip that you're connecting.I wish I could take a video but I don't have a tripod. Good luck!

While being able to open it on both sides instead of just one makes sense, the way these are designed, it is extremely difficult to get it to open in the first place. I tried a screwdriver, kitchen knife and eventually got it with needle-nose pliers. But broke a few along the way. After finally getting it open and securing it to the LED, it was just as hard to get it to close and stay closed. And after all that trouble, it didn't even work at splicing the two strips. The lights did not turn on.

I had to move some shelves on my entertainment center and that meant my led lights didn't go all the way around the shelf with the TV on it anymore. I found the left over LEDs from when I originally installed it and used these to connect it to the main strip and it works perfectly!

After accidentally cutting our LED strip lights we were looking for ways to fix them versus replacing as they were through our glass railings along the deck. After a few tries it works seamlessly and saved our views. Great idea

It is practically impossible to open without destroying it. I don't know if I'm doing it wrong or it's genuinely faulty but I'm at the point where I'm bleeding trying to get it open because it won't move and it's so small.

La semplicità di utilizzo.

Sehr gutes Produkt kann ich nur empfehlen.
