You need to have a tiny screwdriver to tighten this every time you need to adjust the diameter of your circle. Very uncomfortable to use.NiceIt does what it's supposed to do, but I wish the needle could be tucked away so that it won't accidentally pinch my kidI know these are the cheapest compasses out there, but I honestly expected them to work better. The pencil would not stay in place and the compass was so wobbly that the kids doing a project drawing planets could not make them round. These were not easy for kids to use.Bought for adult use and is somewhat difficult to maintain the circle when using, but was able to get my project done.Kid likes itGood product, came on time.Bought a few of these for the supplies drive we had at work. Wish they had these models when I was a kid.I can't recommend this one for year 4. It is not easy to use for my 9 yo and the setting doesn't stay. Glad it is fairly cheap as I need to find another one he can use for school.Also I was supposed to receive a green one and received a pink one instead... Not goodDoesn’t work because the screw joint is too loose and even after tightening it myself the compass flies open again mid-use in under a minute. I had high hopes for this item because it looks stylish, but it just won’t draw a circle! The loose holding tip requires the wrist to bend down as far towards the page as possible and I personally found my wrist was at its limit. Deeply disappointed and saddened.Sorry to say I was disappointed. It wasnt sturdy enough, fell out of my hand many times tried holding it losely but went all over the place tried holding tightly it barely moved. Couldn't win with this a d will not use it.Using the compass was a bit tricky for the children, and they broke in just few uses.My child struggled to use this product effectively
