Testimonials
I bought four used M30S units from a seller in Seoul who claimed 88 TH/s average. System Ashfield measured two at 81 TH/s and flagged degraded thermal paste on a third. I renegotiated before paying the final installment. The report paid for itself twice over.— Hyeon-woo R., private miner, Seoul
The facility matching session was direct — they told me my S19 batch would exceed the Tier B envelope at a host I had already verbally agreed to. I found a Tier C facility in Ulaanbaatar instead. Wish I had called them before the first host sent me a contract draft.— Priya S., small fleet operator, routed via Busan
Report turnaround was slower than I hoped — five days instead of three because of a lab backlog in September. But the thermal data on my Avalon units was thorough, and the host accepted the documentation without follow-up questions.— Tomasz W., resale buyer, Gdańsk via Busan courier
Used the hashrate verification for a single S19 Pro before listing it on a secondary market. Buyer trusted the signed letter more than my pool screenshots. Simple service, no upselling.— Yuna C., part-time miner, Daegu
Case Note: Batch Assessment Before Kazakhstan Shipment
A Gyeonggi-based operator planned to ship twelve Antminer S19 Pro units to a hosted facility in Kazakhstan. Contract Tier C allowed 3,250W per unit at the rack.
Our 48-hour burn-in logged two units averaging 3,410W at 220V — above the tier ceiling. One unit showed a failing fan bearing that would have triggered a host maintenance charge. The operator replaced the fan locally, reran verification on the two high-draw units, and shipped with our batch report attached.
Three months later, the operator confirmed zero power-tier penalties from the host. Total assessment cost: ₩2,640,000 for the batch. Avoided penalty exposure on two units alone would have exceeded ₩1,800,000 over the contract term.
