Affiliate Disclosure

The Open Current is reader-supported. When you buy through links on our site, we may earn an affiliate commission at no extra cost to you. This helps us keep researching, testing claims, and publishing honest comparisons instead of running ads.

Our recommendations are based on our own research, including manufacturer specs, real owner reports, and conversations with people who actually run these systems day to day. Affiliate relationships never determine our rankings or opinions. If a product isn’t worth your money, we’ll say so, commission or not.
