Nicely made, clear, and very accurate.
Apart from the battery fitting being a bit fiddly, these work really well and make setting up cutting tools and measuring cut angles really simple and precise.

Accuracy ok for DIY’er
Ideal size and accuracy for my DIY jobs. I also bought the Nesoi mitre protractor to compare them. Both very similar with accuracy.

No Batteries included.
Edit - so in fairness to the company, they contacted me and refunded the cost of the battery. (And offered a full refund as well). The product is decent, and does exactly what it needs to do. Based on that and some good customer service happy to go with 5 stars. Felt somewhat disappointed it didn’t come with a CR3032 battery. Not the sort of thing I have lying around the house normally. I’m sure other items of similar price would come with a battery.

great item, difficult battery replacement
bought to replace a similar one that broke it works perfectly and is repeatably accurate....the downside is the impossibly fiddly battery replacement that requires three hands !.... why ????

Seem to do the job, unsure exactly how accurate they are
Bought to replace a set from Trend which were awful. These seem ok. Time will tell.

This unit which I use mainly for woodwork, is very accurate and therefore extremely useful. The readings are identical to my magnetic saw angle meter. I agree with others, that changing the battery is a bit of a pain but I imagine the battery (CR2032) will last a very long time as with other devices such as calipers and depth gauges etc. so not a reason to give it a lower rating as at least it is very firmly latched into place. A pair of tweezers certainly helps and solves the difficulty factor.
