Operator Testimonials

We brought three Antminer S19 variants to Lagoonfield before signing a colocation lease in Gyeonggi. The wattage spreadsheet they produced matched our utility bill within four percent over the first quarter — that alone justified the assessment fee.

— Min-jun H., small-scale operator, Yongin

The procurement brief was thorough, though I wish the lead time had been shorter during peak season. Still, we avoided a batch of refurbished units that would have blown our breaker panel.

— Sarah L., facility manager, Incheon

Choi-san caught a failing fan bearing during the thermal portion of the assessment. We returned the unit to the seller with Lagoonfield's report and received a replacement without argument.

— Tomás R., hardware reseller, Busan

The report language is technical but readable. Our landlord's engineer accepted the power draw figures without requesting a second opinion, which saved us roughly two weeks in the approval process.

— Yuna K., co-location tenant, Suwon

Case Note: Warehouse Expansion in Hwaseong

A mid-scale operator planning to add 40 racks engaged us for procurement guidance and spot-check assessments on six candidate models. Our brief ranked units by watts-per-terahash under conservative cooling. The client selected a model we rated second on raw hash but first on consumption stability. Six months later, they reported 11% lower cooling costs than a peer facility running the highest-hash option.

Case Note: Refurbished Batch Verification

An importer purchased 25 used Whatsminer units from a European supplier. We profiled power draw on a random sample of five units. Two showed consumption 18% above manufacturer stock ratings, indicating prior overclock damage. The client used our reports to negotiate a partial refund and diverted the affected units to a repair vendor.
