Earlier this year, I purchased the A1 Mars Lander. I loved it so much when I got it that I resolved to add a pod miner to it as soon as I could. I had a bit of trouble with it when I first got it, but thanks to the patient and generous efforts of the support team here at Bitcoin Merch, it was deduced that I just needed to run my pod miner with their optional upgraded power supply. They were kind enough to just ship one out to me and once I got it and plugged it in I was off to the races - and have been there ever since - with my now average 1800GH hashing power.
As stated in the title: If you're going to throw your money at this bad boy, do yourself a favor and just dig a little deeper in your pockets to grab the updated power supply with it while you're at it. If it turns out that you don't need it? Fine, you'll have a spare on hand up front. If you do need it, You'll be able to figure it out right away and save yourself the odd month of support and waiting I had to go through to get to that same conclusion.
