Just received my Mars Lander from Bitcoinmerch.com. This thing is amazing. Having so much fun with it. And I can not begin to tell you how amazing the customer service is with these guys. I am a beginner and they have been so patient and understanding. Super fast response time when I reach out to them. Not only do they offer amazing products, they truly put the customer first and ensure you are going to have a great experience. On top of that, the instructional videos they provide at are amazing as well. So happy I found them. If you want great products with great support, you can not go wrong with these guys.
