Excellent product. I recommend it to everyone.
Module is very compact and good quality, it has 2 capacitors which is very good for signal. there are 2 ridges on the corner which are very sharp. keep in mind that the "mini sd card" option is a tf/ micro sd slot. arrived in 2 weeks, recommended.
Module functioning perfectly.
Good quality.
