If I could give you 10 stars I would. I have not had a vendor do everything right for a long time. Your website was excellent, customer service was able to identify the proper item, take my order, notify me of USPS and tracking info, and E-mail of arrival. Package was received three days later. OUTSTANDING JOB !!

Outdoor Sensor Review

The online tool for selecting the correct unit was very helpful and eliminated risk that wrong model might be selected. Shipping was quick. Item works well with my weather station.
(I would suggest a design modification that makes the item more weather resistant. This is the second time that I've replaced the unit over 3 years. I place it outside with little protection from rain and/or wind, so I cover it partially with duct tape, which doesn't seem to interfere with it's function. An exterior redesign could mitigate that exposure.)
