The Noyafa NF-563 Thermometer and Hygrometer has garnered a mixed reception from customers, with many praising its usability and relatively accurate readings for both temperature and humidity, particularly in practical applications like greenhouses and HVAC inspections. At a budget-friendly price of $13, users appreciate its efficiency and the insight it can provide into potential environmental issues without needing to resort to more expensive equipment. Customers highlight the device's easy-to-read backlit screen, which simplifies usage in various conditions. Its light weight and portable nature are also noted, making it suitable for diverse settings, from sophisticated labs to everyday home use. The NF-563's SHT30 sensor is frequently acknowledged for offering quick response times and accommodating a ±5% tolerance for humidity, which some users accept as standard for devices in this price bracket. However, the product is not without its flaws. Some users reported initial accuracy issues, with one customer mentioning their unit read humidity levels 3-4% higher than other more trusted devices. Complaints about reliability include one reviewer who experienced display dysfunction during use, despite workaround methods. Additionally, others found the device's auto-off function hindered its performance, stating that it turned off too quickly for continuous readings. Despite these criticisms, many users feel the NF-563 provides good value for money, especially for non-professionals looking for an affordable, user-friendly option. It is an instrument that, while not perfect, serves its purpose effectively for most casual users.
