Frequently Asked Questions (FAQ)

Comparing Similar Products

I was skeptical about spending this much on a wrench extender but honestly it's worth it. The reach is great and it feels really solid in your hand. Definitely better than the cheap ones I've tried before.

Honestly pretty disappointed. The box arrived beat up and the windshield had a small scuff right in the line of sight. For $172.9, I expected better quality control. Installation was a nightmare and it didn't line

I couldn't get used to the progressive lens at all. Kept getting a headache after 10 minutes. Also the frame felt way smaller than the pictures online showed. Returned them.

It's alright for the price point but the blade feels kinda flimsy if you try to cut anything denser than basic fiberglass. Good for home use i guess but i wouldn't use it for a living.
