Review for Fernox Protector F1 500ml by South Yorkshire Heating

Love Fernox products and these chemicals. I have used this inhibitor for many years and have always been pleased with the results. Many other inhibitors have come and gone but Fernox has stood the test of time.

Mainly use this as I trust the brand. Always had good experiences with fernox. Costs a little more than the cheaper centre brands own stuff but well worth it

It is the standard, can't go wrong with fernox products. There are cheaper products but these guys have been the standard for decades and why would you risk it?

I bought the hilariously small pocket level, to use when fitting electrical backboxes and accessories. It’s been great for these uses, the magnet is very strong and it’s so small it’ll fit inside a standard UK single backbox. I paid about 6 quid for mine, and I flipping love it, even if it does get a few laughs on site.

Had a set of these for a couple of years and they’ve been great! Being stubby you don’t usually have much trouble drilling a nice straight hole when working up between joists or under floorboards. When they’re brand now the absolutely eat through timber. Quite expensive but reasonably hard wearing, they do say they are nail proof but I always try to avoid that as much as possible to prolong their life

These little hole saws are brilliant for drilling neat holes out in thin metals and plastic. I have been a long time user of starrett holesaws but when it comes to drilling out holes in trunking, boxes and panels I’ll 100% use on of these instead! Last a decent amount of time too so long as you look after them.

My favourite torque screwdriver set on the market right now, Wiha have done a great job in making the handle still feel ergonomic in the hand despite it being larger due to the fact it’s got the torque guts in it. Setting it is simple with the included tool, and I think it’s got the best torque range out of its competitors at 0.8nm to 5.0nm. Keep an eye out for deals on Amazon for this, it drops down to around £110 sometimes
