A proper mitre saw
Bought this to replace the awful generic blue mitre saw I've used for years, which is still sold under various brands for £40 or so. The difference in quality & precision is evident straight from the box. Read the reviews for the generic blue saws, they're loose and wobbly, so that cut angles vary by 5 degrees. This Stanley is tight, cuts a lovely clean line bang on the required angle. As always with tools, buying the cheapest often leads to regret. I can go to Valhalla in peace now, knowing I finally have a decent mitre saw.

Good for the price
It works well, for the price and despite the crude blade pitch. On the good side it is cheap and easy to use. it has some design flaws, such as the large gap in the rear support, at the centre, so it's hard to cut small pieces. And the position arrow is 1cm or more from the angle marks so it's hard to line up an exact angle, which in any case is hidden under the saw. But you'd expect to be complimenting a basic device like this with your own vice grips, bits of wood, marker lines and so on. I cut some metal trim to border the roundy bottom of a stairs, to a laminate floor, and it was easy (5, 10 and 20 degree angles).

Great hand mitre saw
First hand mitre saw I've bought in 18yrs, Don't think you can go wrong with Stanley, Good value for money, easy to use very sturdy while cutting, nice size, love the pegs to help keep wood in place while cutting making the cuts very accurate.

Paint finish very poor.
Very disappointed with the paint finish on this product as there are runs in the finish.Everything else seems okay

Great solid saw, does the job
I am building a work bench and need to cut 90 mm x 40 mm pieces of timber at 90 and 45 degrees. I need some accuracy but not anything extreme. I felt that buying a 250 mm power mitre saw would be an overkill and a waste of money. I did not really knew what to expect but this is a great piece of kit and definitely more versatile than a power saw. It is mostly made of metal but the legs are plastic. Still, it feels very solid. It cuts timber quickly and accurately. I tried a 60mm x 40 mm and it cut it cleanly in i think about a minute. This is a great product, safer and more compact than a power saw.

It's adequate
Seems a bit flimsy but did the job. Also you only have set angles you can cut. I actually wanted 9°... Had to change the plan

Excellent value
A lot lighter than I am used to but it’s a solid clear angle reader so I’m very happy with it, a bit of a potch to put together but well worth it, I’m going to put all new skirting boards and beading plus some other things so I’m excited to use it, the plugs are a good idea, fitting practically any sized wooden piece firm. Id recommend it for such a cheap price
