Warning -- these plug adapters break very easily! Fortunately, SSE sends a pack of five. I have used them for over a year, and down to my last one.

Like them, the plastic is the hard plastic so if you drop them as I did they break easily.

They were ok for a bit but broke very soon. I could still use them, but the plastic parts were broken so I just shortened the length. Then, they broke in more places. Buy a pair that doesn't break.

They break easily. I've had to replace them 3 or four times, granted it was part my fault for carelessness, but they just are not very durable. I'm going to find another brand.

These are nice. They look exactly like the picture.

Biggest issue is they broke very easily. Im going to need to buy another pair already. I think Im going to go with a different brand.

they break very easily and once you remove one ball it either snaps or you cant screw it back on.

I've had these for about a month now and I'm down to 4. The plastic breaks way too easily, especially the lids. I wasn't expecting them to last a lifetime, but I was hoping to get at least a few months out of them.
