Apera sent me a replacement probe. Still couldn't get the unit to work so Apera paid shipping to return it for examination. Turned out it was an air bubble in the probe - I was supposed to shake the probe befort use. Apera returned my unit.Apera customer service were very polite & very responsive.I can thouroughly reccommend this company. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/178179365-apera-instruments-yd300-portable-water-hardness-ca2-and-mg2-meter](https://www.desertcart.pt/products/178179365-apera-instruments-yd300-portable-water-hardness-ca2-and-mg2-meter) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-24*
