Tavy spacers

I've been using these spaces for years. I love them. I'm just a little nervous because they changed the color of the spacers. I think they were bought out so I'm not sure if they're going to be the exact same size. They changed The colors the white ones are now 1/16 instead of green they switched all the colors around. I'm glad I have all my old ones

Awesome!

The product worked great!. The effort to break off is much less than the previous product I was using from the orange store. These may cost a little more up front, but the ease of removal is worth it as I had a number of the previous products break off in between the tiles. And that can be a challenge to remove without damaging a tile edge. No doubt will purchase these again.

Outstanding Product

I have used the orange store brand and some clips were difficult to break and some remained between the tiles which can be a challenge to remove. With the perfect Level Master product, not one single issue. It takes much less force to break the spacer clip also. I will purchase this brand again without question. Good quality product and easy removal.

Better than Dewalt and MK Diamond blades for cutting porcelain tile

Before finding the Helix Copperhead blade, I used Dewalt XP4 and MK Diamond MK-415 blades. Both of these blades generally have good reviews, but they cannot touch the Helix Copperhead for smoothness of cut, lack of chipping, and lack of breakout at the end of the cut. I use the Helix blade primarily on porcelain tile and the cuts look factory on rectified tile. My machine is a MK Diamond 10" wet saw with a belt-driven blade arbor. The only non-positive comment I will make concerns the thinness of the blade. It has a thickened center section, which helps the blade run true. However, because of the blade rim thinness, it is possible for the blade to deflect slightly if pushing the tile too fast - an effect that is easily remedied by slowing cutting speed.
