## ⚠️ Minor Issues

### 1. Prices without dates
- Цены указаны без даты
- Рекомендация: добавить "По состоянию на 2026-05-12"

### 2. Specific models not always named
- "Maunfeld MIHC604SF2BK" mentioned but not the recommended model
- Could be more specific for the final recommendation

### 3. No direct links
- No clickable URLs to stores
- Would improve traceability
