"Good retainer for price, a bit bulky"
tbookwalter
Easy to install and easy to use. This is a good retainer for the price and an excellent alternative to the more expensive metal retainers which can cost as much or more than the rocket they are used on. After a few launches of E-G class motors, my first pair are holding up well. My only nit is that it is a bit bulky. On smaller diameter rockets, the closure is larger than the rocket. On one use, I sanded down the ribs to make the model a bit more aerodynamic. I just bought two more packs and plan to use these on all my 29mm motor mounts.

"Best economy engine mount for 29mm"
SteveAwesome (Highlands Ranch, Colorado)
I love the simplicity of this retainer. The price is great and installation / use is a breeze. I will never fumble eith any other type of retention system for my 29mm RMS loads.

 
"Good Budget Retainer"
wplatz
These are the same retainers that come in Estes Pro Series II kits. They work well for scratch built rockets or kits where you would not want to invest in an aeropack retainer, but provide the benefits of a screw on. The only downside is that they are plastic so they can be more easily effected exhaust heat discoloring the cap. Overall they are an excellent value.

 
"Cool product for larger birds"
wallyum (Ft. Thomas, KY)
I started out using these on some of my larger Estes rockets because they were included in the kit, but I quickly ordered some extras when I realized the utility that they offered. Just scuff up the inside of the ring and the end of the motor tube, apply epoxy sparingly, and wait until it dries.
