You're shortlisting condos / HDB units / landed. Each one looks fine on paper. The fengshui differences are real but hard to compare by eye. This product runs the same severity-tier audit on every property you're considering, then ranks them on one PDF — so you can make the call with the same rigour you'd use for valuation or structural inspection.
For comparison: 3 individual Solo audits would be S$117; couple-mode 5 would be S$295. The bundle saves S$18-96 depending on configuration.
