B BLOOMOAK Heavy Duty Circular Glass Cutter with Round Knob Handle and Suction Cup Adjustable Diamond Glass Cutter Tool Set 24" with Extra Blade (60cm)

Works great! It takes a little practice but it will cut a perfect circle.

Works way better than I expected. It was easy to use & did exactly what it was supposed to do

Worked well on thin glass, but I was unsuccessful on thick glass. I've done straight cuts on glass before with other products, but this was my first time attempting / making circles, so it could be me and not the product. The directions on how to snap the glass after scribing aren't great, but we have the internet for that. It made a clean circle scribe with no wiggles AS LONG AS I had the suction cup handle lock going in the correct direction (practice first), and I also had to support the suction cup with downward pressure with one hand, and I checked the position of the blade before starting. Honestly, the directions are kinda silly, I included a picture for a smile. I am pleased with this product, because so far I successfully made 3 circles and I'm halfway done with my project.

Like the size and the way it cuts. So far it's worked on all types of glass. I've even had some circles fall out of the piece I was cutting on. Makes nice clean edges on most glass. Some of the wispy have had some edges but that's to be expected.

I tried to cut a whole in my glass, and it started to fail immediately. The suction cup did not work at all, it would stick for a second but about half way around the circle it would pop off. I went around the whole circle over 9 times and then hit and it SHATTERED THE ENTIRE PIECE even OUTSIDE of my cut mark!! It ruined so much glass!!! Take it from somebody who just lost all their glass, DO NOT BUY

I've been unable to make a 4" hole. It could be me. I made about 9 attempts after watching a dozen or so YouTube videos on it. Circles work just fine.

good quality as advertised

Usually I rave about products but this circle cutter--well, I'm a work in progress. Never really coordinated and not particulary strong, I'm not doing as well as I had hoped. But I'm not giving up; I'm moving down to thinner glass and I got a grinder to help with the slightly uneven edges. I'm sure I will get it and I know the equipment is not the problem.

Good product

Good value, functional and small enough to sit in side of van, holds heavy duty glass too. Was perfect for job in hand which was to fit a sky light

Good solidly made. Here's a modification I did because I bought it for paper, etc., but a glass cutter only does glass. I tapped out the 2 bearing sets from above, and unscrewed the screws in the head(so the drill bit doesn't hit), remove the oil reservoir, and widen the hole with a drill press, best to use drill vice. to widen the size to fit a metal body pen knife with a swivel blade(Amazon link attached). Otherwise the blade will fight the movement and try to wander, etc. Then you'll just need the screw that tightens the size adjustment. You'll need to practice, I held it with pressure at the attachment and made sure I continued in the same direction, otherwise the swivel may effect the cut. Hold the material so it doesn't bow when cutting. https://www.amazon.ca/dp/B0006O5JF6?ref=ppx_yo2ov_dt_b_fed_asin_title

Funktioniert super. Glasschneider ist sehr hochwertig und dazu gab es noch einen Reserveschneidkopf.👍👍👍

la verdad que parece una herramienta fuerte pero le encuentro algunos fallos... la ventosa no tiene gran adherencia y sino se sostiene haciendo preción se levanta y se jode el corte. tambien la punta gira entonces a veces al cortar se dobla hacia adentro y hace que no quede un círculo perfecto. para principiamtes está bien pero buscaba algo más profesional ya que la utilizo a diario para muchos cortes
