Very professional seller who responds immediately to pre- and post-sales questions. The product appears quality, robustness, design, operation. Start-up and connection of a waste pipe are very simple. Formidable efficiency for the capture of moisture very quickly ascertainable. For places with high humidity to install a drain pipe is required, otherwise we spend time emptying the drip tray. I recommend this product for now gives me satisfaction (longevity remains to be seen).
