Screw Extractor 5 Piece Set
Not the best.
I wasn't impressed with this product I used them once (which thankfully was all I needed it for) and it didn't work the material isn't strong enough to do what you need it to again and again. they were expensive but then neither were they cheap.

I've used easy-outs before which worked great, these just went blunt almost immediately and failed to grip enough on low torqued (12-20nm) bolts which I'd almost drilled right through. I'm off out now for a decent centre punch to try that before removing the engine so I can do a proper job. 3 hours of very careful drilling leaving pretty much just a thread and these dont work, buy something else unless your screw/bolt is stuck in a block of cheese.

Worthless bit of kit
Tried to extract one broken 4mm bolt with these. Competely useless, not hard enough and thread on extractor stripped without moving the bolt at all.

Good value for money
Bought these the other day and used them within 2 hours of purchase, they worked well and saved me time and money , so they have paid for themselves so im very happy.... well done Screwfix
