Review for Fernox DS40 System Cleaner by S Banks Plumbing Heating & Eco Energies Ltd
17th September 2019

Excellent stuff and I use this all the time. It has a different colour when adding and then changing colour when spent. It’s a very good product and it’s good for the price

Review for Fernox DS40 System Cleaner by Udell Electrical Services

I used this stuff a few times to clean my central heating system. The house I brought the central heating wasn’t maintained properly and all the heating system was full of sludge and some radiators were not heating up correctly. Used this stuff and it improved the heating ten fold. I also have a magnetic filter on the system too so that picked up the junk that was broken down.

Site fortress safety shoe. Overall review after appropriately 11 months of wear. This shoe eliminates the need for constant replacement boots due to the additional rubberised toe cap area that as any workman will tell you wears through after afew months from constant kneeling. Great value for money and even added an insole for additional comfort. Bargain price from Screwfix for £38. Would recommend these over any standard DeWalt boots. Toe cap feature prevents buying new boots every 4 months.

I only purchased this unit as I had the batteries already and didn’t want to buy another Bosch hammer drill. Breezes through most materials and is and a great bit of kit. As with all Milwaukee it can seem expensive but it is definitely worth the money.

Great drill and reasonably priced if you can find it somewhere on offer. As with all Milwaukee tools it is built to last. Great as a multipurpose drill but does struggle if using in place of a Sds drill occasionally. Same as the driver , great for most materials but can struggle when trying to drive self tappers into thicker metals. As a one drill does all it’s a great bit of kit. I use it for my tool bag if I’m going to quick jobs that don’t require more heavy duty kit
