Review: Will get the job done - I was barely strong enough to clamp them shut which was a good thing. It means they’ve sealed. This was 12 years ago and they’re still working just fine. Spliced in a meter feeder wire to a trailer house.
Review: Amazing. - Gets the job done worked 2/0 and 4/0 wire. the goo gives peace of mind. there are little spots for zip ties (not sure if that’s intended or not) but they fit perfectly. Use vise grips (grip pliers) to clamp it tight and add your zip ties. Flawless Installation and performance been 3 weeks no issues with 50 amp service going through it. Will purchase again if ever needed.

### ⭐⭐⭐⭐⭐ Amazing.
*by J***T on December 11, 2023*

Gets the job done worked 2/0 and 4/0 wire. the goo gives peace of mind. there are little spots for zip ties (not sure if that’s intended or not) but they fit perfectly.

### ⭐⭐⭐⭐ Super easy to use but need to be clamped a little better
*by J***N on June 3, 2021*

I needed this to fix a fault in my underground electric line coming into my house since the wires had gotten cut due to the ground settling. Was super easy to splice my lines and hook them back together. Only problem I had was trying to get the box with the gel clamped together so I just used a couple of zip ties then wrapped the entire thing with some rubberized splice tape I had. Just got everything buried underground again a couple of days ago and so far so good. Got full power in the house again and no issues. Worked great!
