The product doesn't have parameters displayed in the manual. Manual doesn't have proper English and cannot find any online details in it. Very few comments on various tests and not enough operating information from the manual.

Fácil y práctico
Muy buen artículo, aún no ocupo todas las funciones, pero es práctico y fácil de usar, aunque tal vez debería contar con un manual más explícito

The device is great. Price is fine too
The device is great.Price is fine too.It just greatly lacks a properly written instruction in English.I mean these people come up with great product at a great price, what is it gonna take to hire a professional technical writer to put together a comprehensive instruction manual?
