Customer Reviews | 90° Stealth Seamer™, Auto

LARRY BARE, Stone Craftsmen, LLC

  • Customer Rating:

We are blown away with the automatic Stealth Seamer™! This will really speed up our time in the field. What a beautiful seam, we tried it for the first time yesterday on a 34" seam and the customer was more than pleased. We love new technology and you have definitely hit this one out of the ballpark!

DAVID KLIMIS, Designers Choice

  • Customer Rating:

After having a Stealth Seam Setter for a couple of years I would say this is the most durable tool that I've ever bought! We use it daily! After owning one I refuse to make a seam without it! Seams only take minutes to set, and if you have a crown in the Granite it's not a big deal anymore. Before I initially bought it I was skeptical wondering if it was worth the price. I was wrong it's definitely worth double the price. Thank you for all that you do Omni Cubed, and I hope that God continues to bless your business.

KRIS JORGENSEN, Natural Stone Interiors

  • Customer Rating:

They love the way it will quickly fine tune the level of the stone. They also love how much room they have to work the seam and clean up excess adhesive while the Stealth is on the seam. Having the option to run off a 9 volt battery also comes in handy. The quality of the product and the materials used is top notch. This tool is built to withstand everyday use and last for years to come.
