Review on Precision Cutting Made Easy: Professional IMT Pistol Grip Glass Cutter With Oil Feed And Replaceable Heads - 2Mm-12Mm Tungsten Carbide Blade For Stained Glass And More by Richard Gilbert

I mistakenly thought the tube in the picture was oil. it's not, so had to buy some & wait to use.Got my glass-cutting oil and OIL LEAKS OUT CONSTANTLY!I adjusted the cap every which way & now its closed tightly & still leaks.My old non-auto-oil has a brass ball on end to tap glass & this one has a screw cap which has an edge - doesn't work as well.I also am not a fan of the push in blade, I understand it is to pump oil to blade but it's harder to line up my cuts unless I allow a pool of oil to release on my glass. (It leaks very slightly just sitting there, but drips out when blade has pressure on it - with cap closed tightly ).
