Works as advertised. Used on door locks and ignition for truck and locks for the house

Well, this is functional and it works. It is graphite, no complaints. This was a good value for the money. Graphite lube is something very useful for the applications intended for it.

We've been sucking it up with a crummy front door lock for months. Fighting to insert the key like you're cutting potatoes with another potato, turning the key like its stuck in a salt shaker that's been left in the rain, and struggling to get the key out like a thousand demons from the depths of hell are holding on to it because they want to lock up your soul. This stuff though sharpens your potato knife, turns salt into silk, and banishes those demons back to under your bed where they belong.One quick puff (it's a dry powder) and everything slicks up instantly. You don't need a lot though. You're going to see a little fall out as you close the door which will fall on your hands depending on where your locks are in relation to your handle. Not a big deal just remember to use sparingly, a little goes a long way.

Not sure why locks start to degrade but this graphite did the trick! I've had trouble with my door key for 2 years and, having previously been in charge of locking the front door, I was startled when I couldn't get the key back out of the lock several times in a row. One treatment with the powder was all it took! It's as smooth as it was when we first bought our home.

Easy to use. Shake the tube and squeeze the graphite powder into the key hole. Slide the key in and out 4-5 times. The key does not stuck inside the key hole anymore. The problem is the graphite powder inside the tube. Probably the tube is old already and forms many small powder crumb. That will be waste. Otherwise......it does work.

Best Product for Locks

Works well for intended use, helping lubricate some older locks in the house. Key just glides in and turns easily now.Have found a bunch of other items to use it on - bike lock, squeaky hinges. Yeah it’s messier, but spray lubricants just stink.

First time buying a powder lubricant. It is amazing! Wear GLOVES when handling the substance

This worked exactly as described. All my keyholes had become “sluggish” and “sticky”. This product really works!

I gave a 4 star rating because when you squeeze the tube the product just flies out with no way to stop from losing half a tube..wish it came with a brush or pointer so you could better point where you need to use it..

Arrived as described. It is a small tube, but I was surprised how much was in it when I actually squeezed the tube. Would buy again
