Excellent quality product.

Excellent Cable Glands - Used for 2.5mm 3 core TRS cable

I'm not sure how to test these, if they don't work I could electrically kill myself, but they look good, seem to work, easy to fit, but are they waterproof.

great item at fab price and very fast delivery.well done.

Yeah sound Will be reordering again

Nice and easy to use and install. Both the plastic and O-ring seem of good quality, and like they will last outdoors for quite a while. I've used a few of these to run some cables in and out of a shed, 6 months on and the seals are still holding with no further adjustment needed. My 9nly complaint is that the flat washer that goes on the back of the gromit could be a bit more sturdy. However, it can take a surprising amount of force for its size. Overall a great product. Does the job excellently, at a reasonable price. Would highly recommend.

Do the job. Appear quite rugged. Only time will tell.

I have used better. I've used worse. For the price of these, they're ok.
