GOBEST Glass Oil Cutter 175 mm, Tungsten Carbide YG6X (GB-0030)

Easy to use, used to cut 8 sash window glass panes do far. Tip: buy a good metal straight edge, do a trial cut to see how far from the edge the knife scores the glass, and deduct that from your measurements. One straight score, and 3mm glass snaps easily and cleanly

Scores the glass ok, build quality isn’t the best, but is decent value for money. Probably more than good enough for those doing the odd job.

Great product, solid and easy to use and does what it should

Utterly useless! You will have more success using a butter knife to make any impact into your glass or tile. To make sure I wasn’t going mad, I tried this on a piece of plain A4 paper and it couldn’t even score/rip/tear into the paper. Honestly, don’t buy this - you’ll just regret it and have wasted time waiting for it and realising you need to buy a proper tool...

Certainly scores glass, but had limited success with the bottles I got this to cut down. It's difficult to keep the cut level all the way around, I think I'd have been better off spending the extra to get the jig. This would be good for flat glass.

Package was open. Cutter was used and oil cut opened and all used up... very disappointed with my purchase.. I will never purchase again... RUBBISH....
