Except they aren't. €99 for a drill, two batteries and a charger. Aldis are £20 for the drill, £15 a Battery and £15 a charger. It's not that big a difference when bulk orders come in to play. All they will do is buy whatever manufacturer will give them the best deal. The tools have their place, but they have their drawbacks. If one breaks within the warranty period you're pretty much guaranteed to just be getting a refund if you've even registered the warranty. Then you'll be down a tool that you probably can't buy again. These aren't made in Austria tools or anything, They are probably packaged in Austria. The fact that there isn't a parent company attached to them like TTI or Stanley leads me to believe they are themselves resellers. There were rumours that some Ferrex tools were being supplied by Positec (Worx parent company)
Whereas Dewalt came out with their lion tech in 2011, that's ten years of support. You also get a Nicad to Lion adapter if you have some of their older tools. I've used Dewalt all my working life, but if you went to Makita or Milwaukee you'd still be better off buying their DIY versions because you're guaranteed some level of after service.
At the end of the day, a hole in the wall will take a fixing no matter what drill made it. I'm just trying to offer some perspective because people get bowled over by the cheapness of the tool. Whereas if you spend just a bit more money you'll get a longer life out of the tool and thus more value for money and a more enjoyable experience.
