not reliable

I ordered this product because i lost my original surface pro 4 charger. When this product was delivered, I was very happy because it was working as in tented but it did not last for long. This charger stooped working after 50 days from its delivery. it stopped working at a time when I was middle of working on a very important project. I was completely stuck because of this crappy product. I am not a very rough user. I mostly use and charge my surface on my study table. I am really disappointed with my investment on this product. I wanted it to last at least 6-12 months.
