Convenient and accurate 2

The manual is easy to read and allows to use the device almost immediately.
Compared to my textbooks meters pamphlets, nothing to do.
There is a certain inertia that surprises at first, but after a few seconds a red dot appears on the distance you want to know. This card is given within 2mm! Fantastic.
By pressing the middle key is chosen what you want to do: length, area or volume. The + or - keys allow calculations automatically appear.
I paint work to do right now: in 10 minutes I had calculated all the needs for my apartment with surface option.
The Bluetooth pairing with my Samsung Galaxy S5 was done as easily as with the touch screen of my car.
Attention, as all devices using the laser, avoid that a person is in the center where you direct the beam: risk of injury accidents especially at eye level. At least that's what the manual, and there is no reason to doubt.
This device may be a bit expensive but it's super accurate. When I bought my apartment, I paid one square meter too. I have learned that too late of course, when a measuring came to me for another reason. If I had disposed of the device at the time of purchase of the apartment, in the end, I would have made a great economy, the current price of m2 in the Paris region.
So if you can, do not skimp and buy this meter. Anyway, like GPS compared to Michelin maps, it is the future!
