Ex Input:
This is the same exact blade that came with my Ego electric mower. I'm still using the first blade, but BOY does it get dull quickly. I have to keep resharpening with a file. This is the exact same size, but they should have used harder, better steel to make the blade. For this price, it should stay sharp longer. Once you own their product, they KNOW you have to buy their blade. \ Not satisfied. If it were half this price, I would have given it more stars. TOO expensive for what you get.

Didn't get a thorn poking through, but the valve stem is made very weak - it cracked off where it attaches to the tube in less than 6 months of use. I will not buy this brand again.

first time ordered they only sent chair no cords. The next time they sent just the car cord, 3rd and 4th time they sent wrong model cord. I eventually had to buy a 12 volt to ac converter to get it to work. After all that they did give me a refund.
