Large bottle
Large bottle so despite required air gap plenty there. Bottle spout locks so no spillage or drying out.

Decent value thread lock fluid
It's hard to review a product like this, because the true quality can only be seen over a long period.I ordered this for various home DIY projects where I need to ensure threaded connections don't work loose over time. It's a common product available from big brand and small label suppliers.At the current price of £9.99 for a big bottle of 50ml this is reasonable and comparable value to other brands.The packaging is good with instructions and a good nozzle system. I tested this when bolting my bench grinder to the bench and it applies well and just needs a wipe with a tissue after use and the bottle seals nicely.All in all - can't fault it. But only time will tell to be sure!

Does what it says on the bottle
This is one of those products that's a bit difficult to review really as it either works of doesn't work and this one works.As a test, I put a drop onto an M4 bolt about half way down the thread. I then ran a nut down to the drop, wiped off the excess and left it overnight.The next day I was unable to undo the nut with my fingers, but with a spanner on the nut and an hex key on the bolt head I was able to udo it all with just a little pressure so that seemed to be pretty good to me.Price is a little below average for this sort of thing and a lot less than some.
