Review on MakerFocus 2Pcs ESP8266 ESP-01 Serial Wireless WiFi Transceiver Receiver Module 1MB SPI Flash With DHT11 Temperature And Humidity Sensor Module For Arduino by Paul Vanlaere

I have 2 orders for this product. When first ordered, all 1MB chips work fine; left me starving for another order. The second order contained two 4MB caches and two 1MB caches. One of the 1MB has bad usage [arrived by brick]. The two 4MB make up for the poor 1MB I got I think. In general I am satisfied with the purchase considering the unit price. For both orders, the chips came in an anti-static bag, not individual bags as the product photo suggests; ultimately a non-interfering factor. Would I buy again - and will continue to do so in the future. Thanks MakerFocus.
