Easy ordering

Easy ordering, And very prompt service. We ordered the same units in the past and have used him extensively. We are very happy with the high-quality

Great Bread Thermometer

I love the big dial which makes it easy to read, unlike the ones they sell in the stores, which have small dials. I could not find a thermometer made just for yeast and dough. I am glad that I came across your website.


This gift was well received, especially since the recipient picked it out. Got it up and running in time for the good storm (very windy today). We live on the northern coast of California and usually have at least 7 mph winds on a slow day. Today we are having 20-30 mph winds, love the new weather station!!

On time and professional service
