To be fair to Ryobi, their cordless impact wrench is actually very good.

We did a test using my Snapon wrench, against the the offerings from Makita and from Ryobi.
The test was to drive a 200mm decking type screw into a pilot drilled piece of green oak. The Makita was next to useless and only drove it half way before giving up. The Ryobi, did a very good job of almost flush finishing it before giving up. But my elderly Snapon with worn batteries, drove the screws straight into the wood until the head of the socket came away.
For normal use, I would have given the Ryobi pretty much top marks.

As for the belt sander. We can knock four hours off the job of sanding a two bay frame down, by using the Makita instead of the Ryobi. The Ryobi is a very big disappointment, even down to the poor location of the power lead as it exits the machine. It doesn't take much to wear through the power lead as it rubs against the side of rough sawn timber. Placing the lead over your shoulder still doesn't really stop this.
The dust extraction point is also fixed and none adjustable, which can be a pain in the backside.
Its also very underpowered, and has a very annoying trigger mechanism that means that the machine has to stop before restarting. I'd give it a three out of ten.

As an aside.. To prevent power lead wear, I feel that belt sanders, from all of the makes, should come with the first 300mm of the power lead as it exits the machine, covered in some form of spring or coiled wrap.

First of all I have to state that my usage is purely DIY, but I have been quietly impressed with the Ryobi tools I have. The first one, an Ers-80V reciprocating saw, has done sterling service in replacing a large roof (cutting out all the old beams/timbers) and general household duties. Equipped with a 12" Milwaukee blade it will go through pretty much anything.

Likewise the ERH-650 SDS plus drill; it's only had amateur use, but it clearly outperforms my old deWalt hammer drill given the same tasks. And as I got it for £40 when Screwfix has them on offer I consider it something of a bargain.

I'm sure that their limitations would be quickly exposed in the hands of a tradesman, but that's not their intended use.
