Watch the shank size
Worked ok for the job I purchased for. One caution - these are for 3/16" shank drill/extensions. My drill & extensions are 1/4" so I had to drill the balls out. I would also question whether they will hold up with aggressive or heavy use.

Easy to use
Worked well for centering bit in the drywall when I was running ethernet in my house

Quality product, but not sure they work.
These didn't really work for me, it could be from user error, but I still wound up drilling into the corner. I don't think they advertise it's easy to use, but it was definitely NOT easy to use. but I gave it 3 stars because the product is well made, and durable, and it fight the bits I bought them for.

worked well for inteneded purposes
The bumper balls worked well enough for the intended purposes, don't know if these would hold up for professional use, but, they worked well enough for running cat6 cable in my house that was built in the 1960's, we ran networks drops to 3 bedrooms and into the living room.

Worked really well.
Used to drill through floor plates and joists. The only thing it needs is a bigger wire routing hole. When using speaker wire, even 12 gauge doesn't really fit. Kinda dumb but overall, you can make it work still. Bit was extremely sharp and worked great.

Stability
Works exactly as advertised. Prevented my four foot drill bit feom wandering where it shouldn't have.
