I found this product easy to set up with one exception. In order to get an accurate barometric reading, you had to set the level from sea level in either feet or meters. I didn't care which measurement it was set at as long as it was correct to either setting. The seeting read 34 feet or that equilavent in meters (it is a toggle function. I was unable to enter my correct level in either setting. I called company at its supplied telephone number. When I explained my problem to the man who answered the phone, he attempted to assist me, but I still couldn't enter the proper level. After several tries, he finally told me it "it takes practice to change the settings and I should just keep practicing". I finally figured that the exact barometric pressure wasn't that important to me so I just forgot about it. All the other functions were accurate and I settled for it the way it is. Basically I am very pleased with the product.
