My experience with this is that your body position must be exactly right if you want it to give consistent results. If you find that position (sitting by the table, hand at the right level etc), it gives you the reading that is probably adequate

I bought it to check the sound levels and this device does its job well. Looks pleasant too. No complaints

The most important premise to satisfaction is to know what you want. And ordering this I knew. I knew the limits and within these limits I think this is a good item. In fact it is so good that I just ordered another one for the future. I like the fact that there is no button. I can smoke it like a cigarette - without hands if I like. As for filling - not difficult at all. You see, you put the liquid in the metal part, not in the coil with those tiny holes. After screwing it all together the liquid pours into the glass coil section. So there is actually so much room for filling that I did it without needle top bottle. With needle it is totally piece of cake. As for the liquid itself I used 70pg 30 vg and then 50/50 mix. With the first - no problem, with the second the coil struggles with the thickness of the liquid, but I wouldn't say it didn't work. Better use less vg than 50 % though - less sucking strength needed. All in all positive review for this one.

I've been wanting this particular watch for a long time because it's principle seemed to correspond to my nature. I explain. With this watch you don't have to use any part of your brain to learn what time it is. I am pretty sure a smart dog can be taught to tell time from this watch. No knowledge of numbers and their meaning is required. So, I think it is easy on my brain. Couple of little complaints too. The leds are truly bright. So If you check time it will be no secret to anybody, especially in the dark. Also although I learned how to change time, I still don't know how to change date. There were no instructions included.

Works and I can count on it so there is not much more to add
