This is a worth while product for the homeowner who cuts on the weekend or a few times a year. I have a bench mounted sharpener that is now collecting cobwebs. This sharpener is well made and about 1/2 the price of the identical branded one.

About 5 minutes to sharpen a blade. This saves time over bench sharpeners. It knocks down the rakers as you file, another time saver. It does a better job sharpening than my bench mount.

De'longhi hose sleeve fits a 6 inch hose very snug - just make sure and to extent the hose after you put it in the sleeve. Very well insulated. It isn't a huge amount of insulation but it is far more effective than the thin layer of plastic.

This does what it says it will it insulates the air intake hose to your a/c to prevent it from heating up the interior of your home. Also blocks light coming in through the duct.

This works incredibly well. Don't regret this purchase at all. Highly recommend this.
