there is better options
had to make multiple scores to get a clean cut. the scoring wheel is small and when you put some pressure on the handle the bars flex. get the QEP one ... much better with larger wheel. real difference in performance.

Response from RubiExpertMay 31, 2021
Dear Customer, thank you for your feedback and appreciate you taking the time to post your review. At Rubi Tools, we take customer's comments very seriously and we always appreciate constructive feedback that will help better our products. We have different size scoring wheels depending on the material to cut. Start 21 in. tile cutter comes with the smallest wheel (6mm) which is recommended for ceramic and smooth porcelain tiles. However, other sizes are available to purchase separately. Please contact us at rubitools.usa@rubi.com or 305-715-9892 so we can help you find the right scoring wheel for the tile you are cutting. Thanks Rubi

    Quality made but tile does not lie flat on the cutting surface. The rubber pads are low and the tile teeters on the metal braking ridge. Especially a problem when cutting pieces small. The tile will "lean" left or right, so the surface of the tile not square to wheel.

    Works great and on sale $22 now at my local Home Depot
    Used on 18", 5/16 thick floor tile and this worked great. Able to make strips about 1" wide. Makes true clean and straight cuts.Way better than wet saw for straight cuts.

    rubi was great on 18" porcelain tiles
    I used this rubi star 21" tile cutter to cut about 50sq ft of counter top and backspash area for kitchen using 18" tiles and it came out perfect. Trick is quality tools. I recommend this for any one who wants to avoid tile waste. I cut 18x3 inch strips perfectly no problem with this rubi as well.

    The heading says it all. It's. a real piece of junk. Don't waste your time buying it. Can't cut straight if its life depended upon it. So I returned it ASAP

      Quality built
      This tile cutter has solid metal rails, not hollow, the cutting wheel easily adjusts for any thickness tile. Just use a medium downward pressure and she will score just fine then a steady press down and you will have a nice straight break. This is a great cutter for when you don't need intricate cuts and don't want to pull out the big dewalt.

        Not accurate info!
        The box reads that it should be able to cut a 16" tile diagonal cut. Only cuts a 15" cut. Waste of my time!! Home Depot has the correct info on website, however the box should also state 15". Called the company they said well 16" is just an estimate??? My tile is 15 3/4" and it wont fit!

          Saved the job!
          After buying a tile saw and spending hours to put up the first wall, I purchased this cutter. The first one I brought home was an open box and was missing the scoring wheel. However, once I got the missing piece I cut the remaining tile in one tenth of the time. I am not kidding. I only use the saw for cuts that cannot be made on this cutter. The device is very high quality and made 100's of cuts without a problem. I am on to my second job and looking forward to using this tool!
