Review: Seems to work very well for a mechanical device. - I’m not a pro, so probably don’t have enough knowledge to evaluate this device fully, but it seems to serve its purpose very well. The handheld sensor (impeller) is lightweight and very low friction. Doesn’t take much air movement to spin it and register a flow rate. Often times I won’t even use the digital console when I’m just looking to see if I have some air flow or nothing. There’s plenty of modes and features in the digital console, but I only use the most basic ones. There’s plenty carrying and storage case is nice to have as I don’t use it much.
Review: full featured! - works as expected ,easy to use, good software (windows 10 only supported) and is accurate.
