Product review (5 stars): Low cost with long delivery times.  Highly recommended even so.
I wanted some DHT22 sensors for some home monitoring projects and these fit the bill perfectly.  The price was right because they came directly from China, but the shipping was long.  (The listing clearly highlighted the lengthy shipping and so I do not count that against the item.)

Overall, I am happy with this purchase and these items and would definitely buy again.  If I wanted the item sooner, I would buy the same items from a different seller at a higher cost.
