"At the end of the day you get what you pay for and this little countersink was ideal for me as it's not something I'd use very often so didn't want to shell out on a more expensive one.
Used to to countersink screw hole in conti-board, made a nice tidy job and I had no problem completing my entire project with it (building a large vivarium).
Rated this at 4 stars, it's fit for purpose and does the job fine but obviously at the price I would imagine there are better quality ones out there - in my case though I didn't need to spend more on something that will most likely now lie in the bottom of the tool box."
"Bought this after i misplaced my old one. It's fine, but that's about it. Out of the packet it was hardly the sharpest. After 30-40 countersinks into MDF it's served its purpose and will be thrown away."
"Bought this to replace a rose bit I had for donkeys years that finally went. I only used it a couple of times before it's cutting edge lost the same sharpness it had on the first go. It still works, but you have to spend a bit longer drilling and apply more pressure to get any where with it. For the price it's ok, but I would not recommended it to somebody who wants to use it on a regular basis."
They are 'cheap-as-chips', but they need sharpening regularly ( I use the grinder on my Dremmel to reasonable effect ). As another reviewer stated, they soon end up 'burning' through the wood, especially as I'm using mine on plywood.
They do have the advantage of the hex shaft which is great for quick changes of bits, with a hex bit holder, especially if your drill chuck has difficulty tightening properly on round shafts.
If you only use occaisionally and you're capable of sharpening it, then go ahead and buy one.
If you have loads of work to do then pay a bit more, for better quality, as it'll save time in the long run."
"Bought this because it was the only one I could find with a hex shank that would go in my magnetic screwdriver bit holder. I know it was cheap, but I thought that screwfix wouldn't sell a product that was such complete rubbish as this.
Even though its so cheap I can't even give it more than one start for value, because it simply doesn't work.
It really struggles to cut out any wood, it took several minutes to grind/burn out a countersink big enough for even a smallish screw.
I was a bit suspicious when I bought it - you can tell just by looking at it that it has no sharpness at all. I should have returned it there and then."
