Dreadful. Enormous pressure needed to get wheel to rotate. Powder made almost invisible line. Very small amount of powder in container. This product had no redeeming features.
I wish I’d read the reviews before ordering this! Firstly - the instructions are terrible. The plastic cap you remove is inside the chalk wheel - on the underside of the clear tub housing the chalk powder (and the little tub is very difficult to remove). Secondly - once you’ve got the stopper off the tub and reassembled the chalk dispenser, then you have to try and draw out your pattern (in this case just very simple circles on black fabric to make masks). It took many times of going over the same bit of the circle to get the chalk to make a mark, it plucked the fabric and the line was vague and blurred with dust (not sharp/precise). The circles I got where oval and so my masks came up small as I had to cut away some fabric to get the edges to line up. In the end I cut circles out of paper, pinned them to the fabric and cut round them as it was easier than using this!
Awful!! Could have been a one-off, I suppose, but ‘chalk’ compartment was just a mass of dust which disintegrated to nothing as soon as I started to try to use the ‘wheel‘ - no marks appeared on the fabric at all - not fit for purpose. Had better results with kids’ play chalk... Will return for refund next time I’m able to get to a store...
Instructions not clear
Instructions not very good. To use you have to prise off plastic window with chalk inside (quite difficult to remove) then there is a long plastic cap remove this (be careful as chalk will spill out ) and replace plastic window back in should now work well
Getting it ready to work needs dexterity
The instructions do not explain where the small plastic cap is to enable its removal. Once googled, I then couldn't remove the chalk refill from the case. It was eventually forced off with a knife m- not ideal. Instructions and ease of use extremely poor.
