I was very pleased on the timely delivery of the SB-400 Altimeter. I set it and have brought it back to the same altitude several times and it zeros out at the same place every time. I use it in my tow vehicle and wish at times it was a little bigger to make reading easier. 4 stars

Good service, item arrived on time and packaged very well. The item is in my opinion expensive for how small and hard the writing is to read on it at any distance. If mounted to a dash its got to be very close to the driver or its hard to read. But product is as described and works fine. 4 stars
