Good product. A large assortment. But as you know, you never find the exact size no matter how many you have. I did manage to fig two together to make it work. So, it's well worth buying.

Works good for running wires

Nice assortment. They grooves could be a bit deeper and they mixed up in the case during shipment, so I had to sort them back out before storing. The quality appears to be good on all sizes, so worth the cost. It would be easy enough to punch out part of the center to thread wiring through, but strong enough that they should not puncture on their own.

Easy to install. Versatile sizes. Worth the money. Thickness perfect for hole sizes

Great for wiring. I use this in tons of car electrical projects, or just to plug the holes when my spoiler is off. Never had any issues with them not sealing

A very good selection of split rubber grommets for protecting wires passing through a metal panel. I used this to run a backup camera wire through the back of my pickup truck cab. It appears to be water resistant and stays in place well. I've had it installed for about a month with no problems. There are many sizes to choose from and I am glad I chose the selection as I didn't know until the install the size needed. These will fit around a hole cut in sheet metal, not for something thick, as they enclose the metal on both sides. They are a little difficult to install, but with a bit of encouragement they fit in. They seem to be made of good tough material.

Strong rubber. Easy to use. Great price. Great selection.

These grommets are pliable and easy to use, and the membrane lets one use as much or little of the opening for better weatherproofing and abrasion resistance.
