Here is a review of SIMORE product and their customer service and customers treatment......

I got mine dual sim adapter three weeks after I order it. And it failed after third removal/insertion(sim cards were not detached from adapter!!!). I contacted manufacturer and they were very polite and nicely advised my that I am two days out of warranty!!! and they cannot do anything! What a ****** company!!! However, I have to admit that a product is good..... when it is working. But $80 INCLUDING SHIPPING IS TOO MUCH. what I paid it not worth a risk..... I placed my review of their product and they never published it. So be aware...
