Got this as a gadget for my dad for christmas pressie as never know what to buy the parents lol but this im sure he will use well, nice digital display so not only can you judge your surfaces the old fashioned way with the wonky bubble but the digitial display tells you nicely in a few different measurements how much adjustment is needed. Hell stuff his christmas pressie i might keep it lol. Knocked it down to 4 star instead of 5 purely because i think the quality could have been better for the price it does feel very plasticy.
