I had bought it from an electronics store a few years ago for about 8-9€, I remember, and it still works....
It also has a safety feature compared to some others that claim to have it but don’t....
Overall, the quality of the board is good and it’s worth the money, believe me...
Others hurt where the terminals connect because the soldering inside the board comes off...
You just need to be a little careful when it gives you a notification for the battery because if you leave the old one in a bit longer, the readings won’t be accurate....
And regarding the terminals, since they are low quality and break often, get a few more to have on hand...

I had bought it many years ago, I think in 2004 or 2005, it cost 35 euros back then, I still have it and it has never let me down. With its batteries, you forget to worry about them, I think I have only changed the batteries three times since then and that's it! The only thing is that the tips of the terminals could have been of better quality, more sensitive actually, but that can be fixed if someone buys higher quality terminals. I have four multimeters, two analog and two digital, and this one is always my first choice. Just make sure it's the BZ model because there is also the simpler M-830. If someone searches a bit, they will find the BZ model even for 8.50 euros!
