I purchased both the .22 kit and the 7mm kit along with additional brushes in 8mm and 9mm. The cleaning rods are obviously not as good as a one piece rod and are rather short for use with a bore guide. Also the kits are not supplied with a jag which in my opinion is an essential item.
The kits come in a plastic storage box and are a cheap solution for someone who rarely shoots and therefore rarely needs to clean his rifles, alternatively they make a very good travelling kit to be kept in the car or shooting bag.
Would I buy them again? Yes most definitely.
They would be better though if a jag was supplied with each kit.
Low cost and compact.
Useful for travel but not exactly comprehensive.
