"What a fantastic little tool. I tried the Vitrex Grout Out Electric Grout Remover and that was dismal. Moved on to this and I've just completed an area of around 12m2 in approx 2 hours.
The reason for the mixed reviews may be that my grout is quite old (about 18 years) and this came out fairly easily but I have recently replaced a single tile (about 3 years ago) and the newish grout around that was much tougher to remove.
Haven't used the serrated blade just the tungsten carbide. Bought a couple of spare blades but haven't needed them."
"Brilliant tool, should have got one years ago, beats a knife and screwdriver hands down and so effortless. Great price and being able to replace the blades is great too, not like cheaper grout rakes."
"Fitting a new bath and wanted to remove a single line of tiles without damaging the ones above. Works quickly and effectively but does need a bit of elbow grease. I just used the abrasive head and it worked perfectly. The right tool for the job at the right price!"
"have used these for many years , my original one was loaned out to a mate and not returned. small and light so easy to use and keep in tiling toolkit. has a long life if you keep it to yourself. has a very good blade to remove grout easily yet will not cut skin so is safe to handle. I quickly developed a technique to remove grout very speedily with little mess and no damage to tiles. A highly recommended little tool"
"Really good tool, especially for the price. You get two different types of blades with it (Grit-Edged & Saw), so you have to unscrew them first before using it. I found putting the screws back a bit fiddly as the holes don't match up 100%, only slightly off, but requires a bit of patience. For this reason and the price, I bought two. Now I have two spare blades and don't have to spend time fiddling about each time I need to switch.
The tool is solid with a good handle, so you can put a bit of weight behind it if you have to."
"I bought this product with some scepticism. Needn't have worried it tackled the job with such ease. I would recommend this product for cleaning up or removing grout. Just be careful it doesn't slip out of the groove as it will scratch the tiles."
"This rake is the perfect tool for scraping dried grout from the joints between tiles, whether you're re-grouting or just need a tool to clean up the joints prior to grouting this tool is perfect for the job."
"I was also apprehensive about this product, i thought it would fall apart in half an hour. So i wasn't surprised when the comb shaped rake didn't last long, although it worked very well while it lasted (you could re-cut/sharpen the teeth if you had a thin grinding wheel and a vice though). Luckily, there was no need as the grit coated blade was much better. I did my kitchen floor which is 90 tiles of 45cm x 30cm in about 6hrs! The trick i found was to scrape a center groove out with the tool, and then use a stanley blade to scrape the sides back to the tile edge (i got through both sides of a new blade) it is possible to just use the grout rake at an angle so you scrape both sides of the joint, but you have to be careful not to slip as you can easily scratch the tile surface. I turned my grout from grey to white, and there's no trace of the old grout. Recommended."
