I am a repeat customer of Technobit and am completely satisfied with the service and the products.

To start, I was once a doubter because of negative feedback i'd seen about Marto74 and Technobit. However, I gave them a chance and found my experience to be nothing like the ones being posted. I've received every order from technobit (marto74) within the established time frame given at the point of purchase. More so, I've received every chip assembly order in half the time initially stated (as in received within 2 weeks instead of 4).
One of the easiest ways to see why technobit (marto74) is a trustworthy company is the fact that they are still offering paypal as a payment option. PayPal drops the majority of companies that are involved with bitcoin because of the risk and the non-delivery of goods. If technobit was not a good business, then paypal would have dropped them a long time ago. In addition, I've never been charged a membership fee to discuss future technobit products. Call me crazy, but I'd rather not pay a fee to discuss fairy tales.
If you want a company that will under promise and over deliever, then technobit is a good choice for you. If you want to chase possibilities that never come to fruition, then look somewhere else. Finally, marto74 is a genuine pleasure to do business with.
I've given technobit a lot of business because of the quality products, the timely delieveries, and the consistency of products. If a company is going to design a miner based on someonelses chips, then my bet is on technobit because they have a proven track record of accomplishing it.
What other company offers the the same variety of various chip manufacturers miners as technobit does? How many of those companies have actually delievered a working product as quickly as technobit can? Which of those companies only sells the number of products they have, instead of offering endless limitless preorders? If you like working products, consistent delivery, and an honest business, then Technobit is the choice for you.
