Great Product
This device is okay. I tried to use it earlier to measure the angle for my trim, but it didn't work so well. Hopefully when I get to siding it works better! UPDATE: I now have 1 side of my garage done that I was actually able to use this product. Honestly this product is great. I feel kind of stupid however, because I didn't realize it slides through and does both left and right sides. Because the screw is dimpled and doesn't come out, I thought it was poor design, but really it's a poor user. Once I accidentally figured it out that it slides through for both left and right sides, i'm super happy. Perfect every time. Makes me look like I do even better work than most siding crews.

good product, bad amazon description
Although I have not used it, It looks well made, with the exception of loose screw. Fixed that before I even use it. Amazon, on the other had, I thought I was ordering a pair, not so. only one. Amazon really need to work on their discretion of items sold.

Excellent guide!
I read the reviews about this item and wondered about it’s quality, but having to be accurate with cuts on a current project I gave it a try. Reviews said it was flimsy and you could lose screws easily, so I paid close attention to making sure the screws were tight. I love this scribe, it has a great design and is easy to use with perfect results. This item is probably not going to work for you if you find yourself frequently throwing your tools into the back of your truck at the end of the day, or if you give it to your lead man of a large crew. Treat it like a precision instrument, i.e. a laser level or transit and it’ll work just fine. The cutting guide works perfectly with the SS424 Snapper Shears.

Great tool but screw parts were loose in package
Great tool but horrible fasteners. I had to search the packaging for missing parts which I fortunately found. I am doubtful the fasteners will hold during the rigors of siding and only wish they designed it better and less flimsy.

A real time saver, BUT
This worked great. Easy to use. A real time saver Update 2/1/2020 Yes the gage still works great , however for a construction site professional use tool it kinda fragile. Mine is now not useable because one of the screws fell out and was lost on the site. For what this cost it should be made better. Now I have to find a screw that will work to fix it.

Do not buy
The idea behind this product is good. The execution is not. There is too much slop in this tool to be useful. There is 5/16 of slop in the tool, no matter how tight you turn the knob. It needs to be redesigned and better quality is a must. Good idea, worthless tool.

Flimsy and not a tool that you can rely on to do an accurate, professional job. If you want to do a crappy job, use this tool. Don't waste your money, like I did.

I bought this for marking gables for siding and I went to set the angle and the knob spun off and now it won't tighten. Very disappointed after be excited to try it. For the cost of the tool you would hope it would be more durable.
