Very good

It is what I expected. It works fine. Good dellivery.

Excellent product and robust!

We will update most of our projects with this module. Very good!

Very Very Good

Very stable, simple connection, works well even with poor network strength. Many of our projects are using this module, and we will keep using it. Great Itead product.

Still a good product

I use this module for the last 3 years. Still very good and stable. One problem detected! Working above 50 degrees celcius some of the modules got problems and didn´t recovered. Some others recovered and become ok again whem temperature goes lower! In datasheet the acceptable working temperature should be higher than 50 degrees... I will continue using this module.
