good grout remover

This item works well. However, you have to have a steady hand. It really serves its purpose.

Worked OK

I received the grout grabber and immediately put it to work. It worked OK but the grout was very hard since it was near a shower. It was faster than doing it by hand but it was still quite labor intensive. I had a sore back the next morning. Here's a tip. Instead of ordering 4 blades to cut through the wide grout lines I put washers in between the blades and the grout that doesnt get cut with the blades chips out very easily. The blades seem to get dull rather quickley too.

Maybe okay theoretically, but a ripoff in practice

I've just wasted some money and time discovering the Grout Grabber doesn't work worth a (darn). Apply any pressure whatsoever to the tool, and it bends sideways. Despite a firm graasp on the reciproating saw, this "tool" dances all over the place, thus damaging the surrounding tiles. Bad news!!

I'm going to get a diamond blade for my Rotozip and try that. Meanwhile, we're using a Hilti demolition hammer to tear the whole floor out and start over.
