I purchased a single rig back on May 18th.
I purchased the rig because the website said "in stock." After a few days of no activity, I contacted Bitworks and I was told orders would be 3 weeks out. Ouch. I decided to deal with the bad news and continue to wait. 3 weeks past and still nothing. Bitworks has sent out a couple of bulletins on pending orders and has also stated there is a communication problem. Obviously GPU shortage is one of the issues but Bitworks also had some alleged motherboard issues as well.
Since my order I moved from the original address and had to send numerous messages to get my address updated. When it was confirmed Bitworks would update it, I noticed it was still not updated in their system and has not been to date.
The communication has been extremely poor. This is a major downfall of Bitworks. Regardless of the circumstances, if a website says something is in stock, then I would expect some inventory ready to ship. I put a lot of money on the line to purchase the machine. Overall the customer service is terrible and there is not a product out there that can offset that.
In light of the terrible communication and lack of updates on progress. I opted for a refund. The refund amount shown was also incorrect (it did not include the $90 priority shipping I prepaid for). I have since escalated on PayPal, because again, no response.
I was lucky to purchase some cards the same time I purchased this miner and it forced me to learn to build my own. It's a shame for anyone else who might have been relying on this miner. I wanted to share my experience as a first time miner. Hope Bitworks can turn things around but I will not do business with them ever again.
