Aside from their vast selection of items, the customer services experience was great. I was informed that some miners i have ordered were no longer available / discontinued. they offered a refund or and upgrade. something that out performed what i had ordered and discounted enough to where i only had to submit a little bit of money to cover rest. very happy!!

I ordered from vipera tech, and received zero messages from the company for over a month. I was there reached out to by James the co founder and was called a clown for requesting a refund after not receiving a package or message for a month. They were extremly rude, did not want to sympathize or help me out in the slightest bit. Wouldnt recommend purchasing anything.

Thank you for posting this review so other buyers can see which type of customers we DON'T want anything to do with. This is what really transpired. 1) Orders a single M30S on April 7th. Checks out as a guest, so system does not automatically send any tracking information. Customer selects the SLOWEST shipping method, 14 business days, PLUS a lead time of 7 days on the model itself that is disclosed fully on the listing. 2) Emails an unmonitored main organization inbox looking for a tracking number on the 15th of April. Attempts to call once but leaves no voicemail on the same day when an agent does not pick up. Does not attempt to reach out to us via live chat or ever again by any method after this date. 3) BTC halving occurs on April 19th. 4) His unit is sent out on April 23rd, within the shipping window prescribed. DHL sends texts to his phone and attempts to call him to collect $55 worth of customs clearance brokerage fees (not duties... brokerage fees). DHL's attempt to contact customer goes ignored for WEEKS. Brokerage clearance fees apply to Canada, but not the USA. Customer was not charged any import duties regardless. 5) We reach out to the customer on May 5th to remind him his package is awaiting clearance fees payment before delivery. Customer complains about this, then asks for a "full refund" even though he checked out agreeing to our purchasing terms that all sales are final and there are no returns or cancellations, citing he was not given a tracking number and "thought it was a phishing scam" despite DHL calling and texting the proper domain link repeatedly. 6) He mentions he had ordered it from another vendor and no longer needs it (interesting). We ask to see proof that he ordered it or was in possession of the unit he claims he "ordered elsewhere when he didn't hear back". No dice. Big surprise. 7) Says he actually filed a chargeback on the 18th, a day before the halving. Failed to bring this up at all during the conversation. What a coincidence! "All sales are final and no returns or cancellations" are on all of our listings and this is agreed to and reminded when you check out. There are manys reasons for this policy--- so buyers who have second thoughts or watch profits drop don't suddenly leave VENDORS and MANUFACTURERS holding the bag. Bitmain's policy is the exact same as ours and our competitors. When you buy an ASIC, there is inherent risk. All customers need to be aware of this risk. Checking out as a guest means you opt out of automatic notifications. We get 50-100 orders per day... we do not manually email customers their trackings unless they ask for it through proper channels (Live chat is the fastest way) or they have an active account on our platform that receives internal messages and shows on their email. Beyond this, DHL will text your mobile when it is scanned. One half hearted attempt to ask for a tracking number does not give you the right to request a full refund at any point. DISHONEST clown customer who is full of excuses as to why they want to back out of a transaction that they agree upon purchase CANNOT be backed out of. There is a reason the vast majority of resellers don't take credit cards and neither do manufacturers. Exhibit A right here.
As a new miner I have to say Viperatech is absolutely a trusted and reliable source for all components and miner product you can find. I have had a great experience with them and will continue to use them as my go to for new product. Thank you!

Ok! I am brand new to mining crypto and I am still figuring out stuff out. I utilized the live chat first and the agent answered some of my questions. However, I am older, I prefer to talk on the phone. I called Vipera and an agent returned my call two times on a weekend. So far, Vipera is doing well in customer service. It is very refreshing to get a human being on the phone especially on the weekends. Secondly, this company takes credit cards. I am not comfortable sending cryptocurrency to a foreign country which I cannot get back. I know any issues with an American Express card, my money will be refunded. So, far so good! I cannot wait until my miner arrives!!!!!!!!!! Joe Z.
