Query: Ugh!

So not only could I not get this to work on my computer until two years after I purchased it but when i did get to attach it I had a really hard time unlocking it. I've only used this product once and wish I had not gotten it. The only good thing about the shipment was that I had no problems with the seller or timeliness of the shipment.
