I am happy to say this is one of the better personal steam vaporizers I have used. Since it is motorized it produces a constant stream of steam and heats up fairly quickly. Though it does start producing some steam within 60 seconds, I found that it takes a couple of minutes before you get the nice steady output of steam. Once it gets going it is really nice. I think the steam is just the right temperature and it is a fine mist that does not spit hot water droplets which can be dangerous. The steam works wonders at soothing dry sinuses and making you feel better when you are congested with a cold, and it’s a whole lot quicker and more efficient than steaming up the bathroom. I did not see much difference between the steam control setting for small or large particle steam, though it appears more steam comes out when placed in the small particle setting. The adjustable neck does not do much for making the unit any more comfortable to use, but it does slightly change the temperature of the steam. When the neck of the unit is fully extended it reduces the temperature of the steam slightly - when the neck is fully extended the steam is a bit cooler. As with many personal steam inhalers, it is not super comfortable to use because it sets on a table top and you have to bend over and position yourself so your mouth and nose are in the mask of the unit. Ideally it would be nice if the unit could accommodate you while sitting in a comfortable position. This could happen if you hold the unit but it gets heavy fast, so it's better if you just bend to accommodate the unit. Luckily, the steam session only last for 6-9 minutes so it's not that bad. As a side note, I recommend reading the instructions before using. They are short but have some good information about how much water to use, where to add aromatherapy or saline solution, and what the steam controls actually do. I would recommend purchasing the facial steam mask with the steam inhaler as a set if you like steam relaxation or would like a natural way to open your pores and cleanse away skin impurities.
