Great product at 1/3 the price of others.
A well designed product at 1/3 the price of many others, and still as functional and comfortable. A great inexpensive VR headset that would be hard to beat for the money. Buy this headset first!

Better couplers for x and y could make it best.
1 of 1 found this helpful I bought better couplers for x and y axis, vs. the solid couplers. Seems to work better.

Good value for personal use.
1 of 1 found this helpful This Oxygen Analyzer is a good value, and it does work as described even without the English instructions. Initially go to the 0-50% range, attach the rubber bulb and filter tubes as shown in the picture, and slowly compress and relax the rubber bulb pulling air (a vacuum) thru the sensor from the filter tube. Be patient, while adjusting the calibration knob, allow the reading to settle for a few minutes at 21.0% (Nominal Oxygen content of about 25 deg. Celsius air and 50% relative humidity). Then you can hook up your Oxygen Concentrator to verify that it is working properly with a proper Oxygen percentage. I personally would not force air through the sensor module to anything over 5 liters per minute. (Nominal high setting on most Oxygen Concentrators for home use) Also, I would not get any water or high moisture content air in the sensor. Only normal room temperature air at normal humidity levels. Keep in mind that the sensor has a finite useful life, possibly 2 years, maybe more. Anyone that can elaborate on usage and care of the sensor, please enlighten the rest of us. So far the meter and sensor is a good product at a reasonable price for personal home or hobby use.
