RS-1 Laser Cutting Guide/Special Father's Day Gift

I got this product in place on my saw (a DeWalt 713 "type 2," the version in which DeWalt omitted the access panel that formerly allowed owners to install DeWalt's own laser or LED guide) with no problem at all. Like another reviewer, I was installing a new blade (a Freud LU91M010, which I LOVE) so adding the laser guide was a piece of cake.Except that it did not work.I tried installing new batteries, changing how I put it back together...nothing. I'll be returning it to Amazon for exchange, because fits fine and i know from another review that it can work with my saw. Hoping for better luck next time...EDITED TO ADD: returned to Amazon for replacement. Return was easy and quick, and the new laser guide is amazing. I can't believe it was only $10. It works beautifully, was incredibly easy to install, and is a huge upgrade to my saw. I am now a very satisfied customer. I am changing my rating from one to five stars.

The laser cutting guide works nicely to project a red line. It is a little weak in bright light, but still visible. It only gets 4 stars because it is so thick that it does not fit the sliding compound miter saw for which I purchased it. The safety shield is close enough to the blade that there is no room for this device. The only way it could fit would be to remove the safety shield, and that is not an acceptable option.I used it on my old circular saw instead. While it does not project exactly on the cutting line, it does give a visual indication parallel to the marked line, so I can see if I am cutting straight. The device appears to be sturdy and should hold up well. Installation of the batteries was easy as was installation on the circular saw. I think it will end up being a very useful device. I just wish it were thinner so I could use it on the saw for which I purchased it.

I added this to my 10" Hitachi miter saw in about 5 minutes. Nothing much to do - unscrew back, add included batteries, replace washer on the left of the blade with the RS-1. I've posted a picture of the unit when I first started it up.I purchased this on Amazon for $14.95, but it is listed under a slightly different description at $21 on Amazon. I think this may cause some confusion, since the specs are not stated for this particular listing ... anyway here they are:1. This product is the Infiniter RS-1 (I've posted pictures of the unopened carton)2. It fits 5/8" arbor with squared end and internal threading (most saws, particularly at the lower end like mine)3. It is activated on/off by centrifugal force (turns on when the blade is spinning)4. The insides are very simple -- a laser, 3 batteries, centrifugal switch, and small board (I've posted a picture of the inside of the unit)5. When you take off the washer that came with your saw, tape it to your user manual; you will be less likely to lose it (picture added)

This is totally useless. The line is so dim that it is not visible in my garage with the door open. I thought that the batteries that came with the device may be bad so I bought a new set of batteries but the line is still so dim that it is not useable. Unless you plan to cut your wood in the dark (I would advise against this), do yourself a favor and avoid this product.

It is far from a precise accessory to your saw. It's perfectly fine for rough cuts on my miter saw. Seems to be about 1/16th an inch off (which is expected since it mounts to the side of the blade). Like I said, great for measuring quick rough cuts, but don't expect precision. Not bad for the price paid.

Fit my Bosch CM12 fine. Laser was accurate. It stopped turning on after 2 days. Checked battery connections and dust. Still not working. Will be trying my luck with the Irwin.

I bought this laser guide because the original laser in my BAUKER miter saw became unusable.I thought installation could be difficult but I took the risk. After receiving the unit, I begun to install it and surprisingly, the installation was much easier than I thought.The biggest surprise was the initial trial. As instructions said, I started with some small works to get experience and the results were beautiful.As some other reviews said, this laser guide permits almost exact cut. Much more precise than the original laser from my Bauker.There was no need for adjustments. When you draw a correct signal and you place the marked piece directly below the laser light, the cut is precise at the right side of the mark. I can not imagine a better work.Thanks to the people who invented this gadget.

I added this laser cutting guide to an older miter saw that did not have a laser guide. Installation was quick and easy and it worked right away.Once the saw blade starts spinning the laser line appears. The laser guide was accurate but only on one side of the saw blade. The side where the guide is installed. The other side will be off by the kerf of the saw blade you are using so keep that in mind. Small drawback for an affordable upgrade that will work with most miter and circular saws with a standard arbor.
