Good thing, but unfortunately absolutely not robust

I have the scale used for a few months successfully on walking tours. Really very good thing, especially in the mountains - I had a few months no longer horizons align (or, worse, to ask me how because now exactly run). The tone is a must for me, with no sound I could not use the scale.

Unfortunately, I stopped in late summer the tiny on / off switch. I can not turn the part now. And since then, thus significantly complicates the operation has (batteries out / in), I no longer use the balance.

I, however, since every now and then have to straighten horizons, I'm going to buy these scales easy again. So expensive it is not luckily.
