Their rotary tools are great , the non Shcepach made one ( depending on the year ) works with Bosch 12v batteries as well. Unlike elsewhere in the world , Aldi don't sell spare batteries and chargers here in the US so it's very hit/miss.
I bought a 20v weed whacker from Aldi , included one battery , 1.5ah I think. I figured I use it twice a year for a specific task and that it would be ok with that battery , it isn't , I can't buy more batteries and it's a little frustrating.
Lidl too ,one recently opened up in Yonkers and unlike Aldi , Lidl sell batteries an to chargers for their tools and have a more consistent selection. They recently had $7 offset wrench sets 6-22mm , $25 creeper /chair and a few things. I have not bought any power tools from them and don't really plan to.
Sometimes I buy a 4v or 12v power tool from Aldi though especially now that I know which ones can fit Bosh batteries but won't buy anything 20v from them again.
