good product

This guide is a decent tool at best, as it's difficult to line up with where you want to drill your holes as it has no centering guide lines or marks and is difficult to clamp down once you get it lined up where you want it. Also, the guide is hollow and will flex / warp out of position if clamped down to hard. 2nd the guide holes are metal tubes that give a snug fit to the drill bits and they need to be predrilled / dressed with the proper size drill and a lubricant for a smooth action and to avoid binding drill bits while drilling holes.

The hole in the drill guide was too small for the drill bit used for the intermediate sleeves. I had to drill out the bushing in the drill guide to make it work.

Works well

This is imperial but the drill bits they sent with it are metric. The levels were installed by blind chipmunks with Tourette's syndrome. But I have bits and don't care about the levels myself. Other than that, it should serve its purpose.

This was not purchased to install a cable railing system. And maybe that's why I am so confused. The smallest drill 3/16 loosely fits all the small guides. The other two drill bits (very) loosely fit through only the 5/16 & 3/8 inch holes. Other drill guides I own are a perfect fit, impossible to miss align. Later I will mic the holes and the drills to see what's going on. May have to return them.

Extremely difficult to line up angled holes. Center lines are not marked. Cheap plastic. Design flaw for the 30 degree angle. It's actually 60! Oopsie.They should take this off the market.

the metal sleeve on the 3/8s for the 45 degree angle is very thin and has almost warn all the way through after just 8 uses.
