Pros:Price - cheaper than the cheapest panel meters.Size - Its small, but not microscopicUsefulness - It make a job that would normally be difficult with a multimeter very simpleBuild - OK, so its not in a box, but the soldering is spot on. Idea of using clear heat shrink is brilliant for this device.
Cons:Can't think of a single one (must be a first)
Other Thoughts:A modified version of these that could monitor the level of a 12v SLA would be nice.
Bottomline:If you have any battery packs with the balance charge connector, then buy one of these now, go on, what are you waiting for?

works for my 3 cell lipo's

Pros:PriceDoes what I need it to doLightweightPortable
Cons:Long wait in shippingWorse yet was the stocking time while waiting for the supplier to make it availabledon't have any con's on the item itself
Other Thoughts:perfect tool to keep my batteries from discharging excessively and wearing them down prematurely. this tool will help extend the life of your expensive lipo batteries (which would be cheaper if you bought the DTW lipo's)
Bottomline:cheap stuff but you risk the chance of having to wait longer if your items arrive damaged since they are located on the other side of the world from the United States (where I live)

Very nice and small.

Overall Rating:
Pros:Measures 2S to 6S LiPo batteries (up to 25Volts). Nice bright display.
Cons:Can't measure single LiPo cell. Minimum is 2S (it take power supply from second cell). The error is up to 40mV (0.04V) on some cells.Measuring results of my sample:1C -> measured 4.18V, show 4.16V2C -> measured 4.17V, show 4.19V3C -> measured 4.18V, show 4.22VAll -> measured 12.54V, show 12.6V
Other Thoughts:The accuracy may be better. Buzzer for low battery will be good. The bottom left pin when display is top/right is black wire (ground).
Bottomline:Buy it. The accuracy is enough for fast field testing of battery.
