This security torx set is labelled by Sealey as "impact". That's something it most definitely is not. At the very best I'd put it at the 'car boot sale / cheap market / pound shop quality tools. I'd have been better off spending around half as much and buying a US PRO set. They would come in a nice blow moulded plastic case too.
Now, I wasn't expecting Snap-on or Britool quality by any means, but just not outright lying on the packaging would be a step in the right direction.
Save yourself some money and give these a very wide berth.
