    MODDIY had exactly what I needed; PTM7950 and Thermal Putty Pads for repairs on my Alienware X17 R1 laptop.

    Fast, accurate, efficient. The only issue is that the cable caused a motherboard overheating and a shutdown. I hjave to return it to you for a refund. Where should it be returned?

    Shopping experience was great, we’ll see the product I receive before I’d really recommend you. But I’m very hopeful.
