I have wanted something like this for years. It's a pain using C clamps and a board as a guide. Nothing works as well as you want and the clamps are finicky when trying to be precise. I recently purchased a small circular saw for cutting large format (2 x 4) tile. Clamping a straightedge to the tile just adds pressure for chipout. This works flawlessly, and if not abused will last me many jobs. When I consider that 2 tiles cost more than this tool I say this is the deal of the century. I made a flat tile holder out of 4 x 4s. Being planed dead flat tiles don't tend to crack near the end. The V groove is access for the blade and the off center cross member is for smaller tiles.Update. I was wrong. Tile dust got in the plastic clamping mechanism and locked it up solid. Only took a couple cuts. It's also thick to the point that I have to raise the circular saw up an that only leaves 1/8 inch below the tile. So ..... for wood it would probably be great not for tile.

I got this with the saw guide, to make an "affordable track saw".Works pretty darn well for that purpose, once you get the edge guidealigned with your saw.BIG TIP:The clamp always seemed to be "sticking". Sometimes it would slide easily, butoften it would jam up and stop sliding at all. It took forever to figure out the trick.Now it slides easily all the time. The trick is this: * The orange part of the clamp has two little tabs sticking out at the back end. * I had no idea what they were for, and none of the instructions mentioned them. * You put the heel of you palm against the back of the gray handle (in the "open" position), and then pull back on those tabs with your fingers, as though pulling on a hypodermic needle. * Voila! The internals of the clamping mechanism (whatever they are) COMPLETELY disengage, and the clamp slides freely in its track.Important Notes: 1) In the pictures, the "edge guide" looks like thin tape that could go anywhere. It's not. It's a nice, thick piece of plastic, with adhesive on one edge so it is ready to apply, and there is cut-away on the bottom of the clamp to attach it to, so it works well. 2) You NEED the edge guide. If you use the clamp for cutting sheet goods, you darn well want that edge guide in place. It is the ONLY good way to align the clamp for cutting. (There are blade-markers on the saw guide, but they're not really useful for lining up the cut when the saw is on the guide. (If you take the saw off, they may work. I didn't.) 3) To attach the edge guide, it's best to remove the clamping mechanism. (Easily done by taking out two screws. The instructions don't say that (they could use improving), but it's pretty easy to figure out there is no way to attach the edge guide the full length of the clamp, until you do. 4. The tape on the edge guide doesn't QUITE go to the end. It's maybe 1/4" short, but there is an inch of extra tape, so do yourself a favor and cut off the end of the guide where there is no adhesive, before you start applying it to the clamp. That will remove the slight tendency of the edge to lift up--something I may have to trim off, eventually. 5. Don't bother with the T-Square attachment! Total waste of money, if you're using the clamp as a track-saw. (For details, see my review of that attachment. It works fine when it makes a "T", but it has to be in an "L" configuration to work with your saw. And in that configuration, it fails miserably.) 6. Now that you know you CAN'T depend on the T-Square for alignment, and you MUST have the edge guide in place, do yourself a favor and mark BOTH sides of the panel you're cutting. Then put the clamp in place, and cut away. You'll save yourself the half-panel I ruined before I figured out those steps. 7. But there is still ONE MORE PROBLEM to solve, if your saw is like mine. The edge guard projects 1/2" beyond the edge of the clamp. The instructions for mounting the saw to the saw plate don't SAY to put the blade as close as possible to the edge of the plate, but they should. What they DO say is to make sure the blade guard is free to move. That's a darn good idea. BUT... On my Ryobi saw, "reasonably close" puts the blade 3/4" from the plate. The blade guard is pretty thick where it is close to the plate, so I can get it the saw MAYBE 1/8" closer, while still being able to move the guard. I KNOW I can move it 1/16" of inch closer. And I MAY be able to move it 1/8". But I NEED it to be a full 1/4" closer, for the edge-guide to be of any use. In "short" (pun intended), the edge-guide is 1/4" too short for use with my Ryobi circular saw. Will it work with other saws? Don't know. But I would check the width of yours. If your blade guard is more than 1/8" from the edge of the blade, it won't work. There is a WORKAROUND, though. So check your saw before installing the plastic strip that comes with the clamp. If it won't be wide enough, double-sided carpet tape and a strip of linoleum are the perfect size. Here's the procedure: a) Get a linoleum remnant from your nearest big box store, along with double-sided carpet tape. b) Cut a 2" strip of linoleum the length of your clamp. c) Put double-sided carpet tape in the groove under the clamp. d) Turn the clamp right-side-up and use your razor-knife to trim the excess tape. e) Turn the clamp over again, peel the backing from the tape, and put down the strip of linoleum, shiny-side pressing into the tape. f) Find a nice long piece of wood you can cut the end off, and do it.Voila! You now have a perfectly-trimmed edge guide!

Overall, it’s a good tool and works as advertised. However I was a little disappointed in the build quality. The clamping mechanism feels a little cheap and not as durable as I’d hoped. Also, you really have pay attention when locking the clamp that the opposing end did not slip. Because the clamping edge is only a few inches wide, it’s kind of difficult to square up the far edge of the clamp. It’s not nearly as fast to get the track setup square for your cut line. It takes a little patience and a double checking of your measurements before locking the clamp in place. Once set, the straight edge is awesome and produces great cut results. No need for the track sled in my opinion. The fence edge is plenty high enough to keep good contact with your circular saw, router, or jig saw. Overall, I do like it and would recommend it, but it could be a little beefier and with a wider edge clamp to help keep it square when getting it set up.

Perfect if you don’t have a table saw. Just clamp and saw. Made a difficult project much easier. I can now cut down full sheets with my circular saw. I recommend a good battery circular saw to go with it.

Easy to use, sturdy and handy. Easy to use with 1 hand and allows me to be far more accurate with my cuts.

I’ve had this for about 4 months now. When it works, it worked well. However, it doesn’t release well it gets jammed often which can take several minutes to resolve. I usually have to give the clamp mechanism a few good whacks before it will release. This slows down my progress and turns what should be a fun hobby into a source of frustration. I will be looking at alternative products.

I really like this system, it gives me straight cuts with ease, but 50" is smaller than the length due to how the pressure clamp works, so you end up needing the extension, so spending 139 for the system with the saw holder extension + this and the angle clamps is a better deal.

Where was this thing all my life! I struggled for years with the old-style primitive straight with the turn type of clamps. But the single clamp does take some adjusting to. It tends to hang up on itself. But after you get used to how to work it, it's great! Highly recommend it.

As described

I really like that it is 3" wide giving you a secure clamping, it does not slip as you make your cuts.

Searched internet for best straight edge with clamp. I came across Bora product line and read numerous reviews which I agree with, were mostly positive. The NGX 50 Inch w/clamp is made of sturdy aluminum material and is very solid. It is easy to use based on its design of having a fixed mount grip on one end and adjustable sliding clamp on the opposite end. Its design of a simple lock and release mechanism at the adjustable end makes it easier to quickly slide and lock the clamp to the desired position. Once locked it does securely hold whatever object I was working on. I choose this model over the previous model for that reason and I am glad I did. Ease of use, quality build construction, including the hard plastic ends used for clamping, truly makes this item worth it's price. Very happy to have come across this product!

I use this when I have to rip down boards or sheets, it works as advertised. I'd love for it to be longer though
