High Price .. Low return .. Look Elsewhere for a VOC meter
I own a ventilation business and offer IAQ testing as an optional service. The meter worked fine for a few months, then was put into storage while we focused on a big contract that took many months. Once we returned back to air testing, the machine appeared to not function properly anymore. Currently it's 100% unusable as the results continuely appear as 0 for both VOC and HCHO. It can be common for HCHO but to see 0's with VOC is extremely unlikely to near impossible. To test the instrument we placed it next to a scented candle which will always provide results and it's shows nothing again. We paid nearly 500$ with taxes to have used it maybe 30 times. I had an earlier also with another Extech product the CO2 which became also defective recently .. but was handled very professional by the company and was replaced. However this time I'm curious to see if I was just lucky to have a understanding staff member or does the company fully stand behind their products. Currently for a product so pricely with a short life span I give it 1 star. If this happens to be just a defective single product and they handle my request professional and replace it without a fuss I will be happy to change my review .. however for the moment I do recommend to purchase with caution.

Convenient, but not accurate
Bought this based on good reviews and price. However, I took several readings with it that made me suspect, so I compared results to a far more expensive model (over $4000). While I didn't expect perfection from this, it was typically reading at levels 2x to 5x higher than the more accurate and calibrated model. In a home built in the mid 1980's it was giving readings over 0.9 ppm (no new paint, carpet, cooking, furniture, etc in the home)! I loved the idea of the convenience, and would accept some level of difference (say a range of .07 to 0.17 for something measure 0.12), but the wide discrepancy this has from reality make it unusable.

Useless. Tried testing air quality in house
Useless. Tried testing air quality in house, in car, outside, I expected it shows relatively stable readings. But instead after the count-down-to-zero ends and the meter is supposed to do the real measurement, the readings keep decreasing until to nearly zero, even inside a smelly closed-window brand new car in a hot summer day. Trusted the EXTECH brand, so ignored the paid 4/5 star reviews. Unfortunately this product does not meet my least expectation.

Good idea but not realistic
Real-time reading of vocs is not accurate and there's not a device on the market that can do that. Lab testing is the only real solution. Tried it as an experiment.

Extech VFM200 VOC/Formaldehyde Meter
I received this through the Amazon Vine Program. Here is what i found: 1. The unit is very nicely done! The power charger unit has multiple country plug ends that quickly change out so that you have the one you need. Not sure how many people will need multiple country plugs, but they are there and it also means that you can order this no matter what country you are in. 2. The included Lithium battery is not fully charged, as would be expected. So, i plugged in the charger as instructed. That brought up a major disappointment in the fact that there is NO charging light!! It also does not bring up an indication on the LCD that it is charging. So, is it charging or not? Is the plug you plugged the charger into live or not? The only way to tell is to turn the unit on after a bit and see if the battery indicator shows more bars of battery life. 3. With respect to usability, the unit is very simple to use. One thing that can be confusing is turning the unit off. They state that you should use a long push to turn it off and the unit will count down from 3 to turn it off. What they mean is to HOLD DOWN CONTINUOUSLY on the power button during the count down!! if you do not, it will not shut off and you get to start again to turn it off. If you do not want to bother with that, the unit will shut off in 30 minutes of no activity. The display is large and very easy to read. You can easily set alarms for points where you want to know if it has reached and they are easy to silence. The only thing to keep in mind that this is an instant read and NOT a cumulative device. So, if you are walking around you can have wildly changing figures if you walk through areas of volatile materials as they are probably not evenly dispersed if they are in use. Walking into a room with a new rug that has been down for awhile gives a more steady reading. Not a problem as long as you know it will do this and know why. All in all, this is a very functional and easy to use piece of gear that has extras like a nice carrying case and multiple plug ends for most countries.

Simple to use meter
Easy to use, gave peace of mind that all the areas I had suspicion about checked out as below threshold levels. Seems to respond quickly to new measurement locations. Takes a minute and a half to "warm up" and get consistent readings, but that's not too annoying. Rechargability is a nice feature so you don't blow through batteries. Light is good, and display is readable and angles. To turn it off you have to get the bottom part of the power button, which is kind of odd. Biggest downsides are really that it's made of plastic, and there's no simple LED charge indicator

Returned VFM200
Box was previously opened and I suspect returned. Found the sensor readings not working or not working anywhere accurate enough especially at the lower VOC and Formaldehyde levels ... comparing levels to one other gas detector. Two decimal accuracy ... ideally should have three for lower hazardous levels.

Helpful tool
Like the alarm feature. Use it in my residential air quality tests.
