Handy
This can come in very handy for various tasks. As a DIYer I often work alone and constantly find I'm missing a "third hand". This device often saves me grief. The sliders are easy to set and can hold a screw long enough for me to get the power driver on it. Repetitive marking out is a doddle. The integrated levels come in handy, as does the mechanically locked T square and friction locked multi-angle bevel square. The only (minor) gripe I had was that the centre of the slider groove was not marked on the main bar, so I had to use offset measurements. Great little gadget. PS-Dear SAKER, for your info it is not a king or an emperor - it is a RULE not a ruler

Good piece of kit, works really well not exepsive. you really need the carpenter pencil from saker as well if you want to use it as a horizontal marking gauge

Handy Tool and Easy to Use
Really useful little tool that makes drilling and marking much easier. Feels solid, adjusts smoothly, and helps get accurate positions every time. Great value and a handy addition to the toolbox.

Great value for money and works well
really easy to use and loads of features that are really helpful. drill guides help consistent and accurate each time. Nice lock to 90 degrees and easy to read scale - good size and well packaged on arrival. easy to set up and lock and great set of features.

When size is an advantage.
This is so useful! Initially, it seemed bulky but the large size of it is its strong point and is the reason it can be so useful. However, as with most adjustable tools, it is always advisable to check their accuracy especially at the extreme setting or if they've been dropped! I don't think I'll be having any spinning drill bits anywhere near it.

A useful tool, needs a few minor improvements.
The tool should be handy, on inspection it appears to be fairly well built, my only criticism is that the numbers which indicate the bevel angles are painted on (all other numbers are engraved/etched), by opening and closing the bevel gauge once, the numbers have scraped off.

A great starter tool if your not too sure you need one.
Very good and having a t square that didn’t cost a fortune.

Great quality and love how it helps me make sure my pictures are not cockeyed now lol helps align them perfectly. Super easy to use and very functional. I use this for way more than hanging pictures though. I use it in my shop to make sure I have the squareness correct in a lot of projects.
