The caviar blade changed my life. Hundreds of porcelain mosaic cuts without a chip in sight. Not enough o’s in smooth to describe this gem. Thank you for making awesome tile products :D
Bought this grinder blade expecting to get some work done — not audition me for a pirate movie.
About half a day into use, the blade decided it no longer believed in structural integrity and exploded and achieved turning from tool to hazard. Sparks, fragments, and life flashing before eyes… , and after an experience like this you may not have eyes anymore.
After this blade became a cloud of bad decisions and almost doing permanent damage. I figured I’d write this review. Survived, eyesight clocked in for work today, and the blade is now in multiple fragments.
If you’ve ever wondered what it feels like to stand next to a small, angry fragmentation grenade, this blade delivers that experience with zero warning. Safety glasses highly recommended — preferably ballistic-rated. A welding helmet, riot shield, and a priest wouldn’t hurt either.
Build quality feels like it was forged from recycled soda cans and optimism. Assume quality control consists of shaking the box and saying “eh, good enough.” Maybe it was rushed, since there was a wait.?
Hey, glad to hear you have both your eyes still. Was wondering if you'd be interested in writing some of our ads and promotional emails? Love the story telling and you have a flair for the dramatic. I think we'd make a good team! Let's get you on board. In regards to the blade, please let me know if you have reached out to sales@crownetools.com as they will take care of you by either processing a full refund or getting you out another hand held grinder grenade.
Sorry to hear that. Wish I knew what exactly you were cutting that could cause that. Obviously we do not want to sell a defective product and if they both were you are extremely unlucky. We'd like try and figure out what went wrong here so that we can ensure no one else has the same experience as you did. Have you emailed sales@crownetools.com?
