Have to agree with you @oddball
Just tried out the products I bought
Molotow 2mm and 4mm I can see these coming in very handy
Also bought the deluxe eraser kit
Peeps if you are looking to buy an eraser I will highly recommend this one.
I already had a derwent one which was pants, wobbled when using as internal holder was just a piece of plastic, eat batteries within minutes.
This one has a much fine rubber, also loads of spares to get you started, a spare rubber holder. The piece that holds the rubber in is a metal ring, doesn't wobble and comes with a power supply. The only down side for me is the power cord is a bit short, but I'll find some fittins and extend that. The power is also pretty constant with minimal decrease when erasing. Wish I had bought this one to begin with.
Well I have all the kit now, just need to learn how to use it.
