Client Reports & Testimonials
What operators say after independent miner assessments—and two detailed refresh project write-ups.
We had three Antminer S19 variants on a spreadsheet from our distributor. Lagoonhub ran the refresh assessment on two of them and flagged unstable hashrate on the third after hour eighteen—exactly the unit our CFO wanted to bulk-order.
— Min-jae H., rack lead, Gyeongsang warehouse
The written report was blunt about fan noise, which saved us from placing units near office staff. I wish the thermal section had included more photos, but the wattage tables alone justified the fee.
— Yuna Park, independent farm operator, Busan
Quote review caught a warranty clause that required RMA shipping to Shenzhen at our cost—something our sales rep glossed over on the call. We renegotiated before signing.
— Joon-ho Kim, procurement, Ulsan co-location
Hashrate audit showed fourteen of our older units still above the 0.05 TH/s floor we use internally. That pushed our refresh timeline back a quarter, which was inconvenient but honest.
— Hye-rim Seo, operations manager, Daegu
Project: Changwon Warehouse Partial Refresh (2025)
A 64-unit facility planned to replace half its fleet during a scheduled two-week power upgrade. We assessed four shortlisted models in the lab and recommended dropping one entirely due to fan bearing noise that would have violated their landlord's amended lease appendix on acoustic levels.
The client kept 32 existing units running, purchased 28 of the top-ranked model, and used the report's wattage tables to renegotiate their power contract before install. Total assessment cost was recovered in avoided acoustic retrofit quotes alone.
Project: Busan Container Yard Fleet Audit (2024)
An operator running modified intake ducting needed to know whether underperforming units were heat-related or pool misconfiguration. Our benchmark audit paired remote pool sampling with a single on-site day measuring inlet temperatures against hashrate dips.
Results showed three units with failing PSU rails rather than thermal throttling. The client repaired those instead of refreshing the whole row—a outcome they said they would not have reached from pool dashboards alone.
