Product Reviews

Excellent product for a great price

Excellent product for a great price. Thanks for the warning that it would take many turns (my words) to see any change in the voltage output. Once I got there, I had no problem setting the level I needed. Thanks!

Really nice and works well

Really nice and works well. Easy to install. I only dropped a star due to the slow shipping, it took about 3 days for them to get around to putting the items in an envelope and sending them out.

So far these are nice, small, accurate, and bright.

Use this for a custom small battery pack with built in charger project. It’s always good to be able to meter your working voltage on your projects.

Excellent quality

Surprisingly bright display. They are quite accurate when compared to the reading on my well calibrated multimeter. I was really surprised at the quality of these small units. I have no qualms about recommending these to anyone needing an excellent readout.

Perfect! 3-wire is important because as long as you provide power, you can read the voltage all the way down to zero.

Super bright.

These tiny voltmeters are amazing! They are extremely bright and clear and easy to mount in tight spaces. Get them.

great little devices

great little devices, for best results hookup the power lead to the highest volotage to be measured, and then the sense line to the desired measurement point. works great.

Good Product

Have used these to monitor voltage of trolling batteries, and other batteries on mowers etc. Very Useful.

No complaints, very happy

Fast shipping, good product, works great:)

Five Stars

great good for me

Just what I needed

Super fast shipping, and product works perfectly. It takes a couple minutes to set the potentiometer on the right position and you must have a voltmeter/tester handy to make sure…

Works great

Good as-is for my custom project

I can highly recommend.My set needed no adjustments, but I didn’t need 1/00VDC accuracy.I built a variable power supply to outputs 3 different DC Voltages which…

Got them in the mail this week. Only got a chance to hook one up and see it work. This is just what I needed for my project.

These little guys are freaking cool. Once I figure out more ways to use them I’ll have an excuse to get another pack!

These are just cool, work great

These are just cool, work great. Can’t comment to longetivity but the price is right and so far so good

Five Stars

They work well so far. Calibration works too.

Perfect for my hobby!

Small and bright blue display, I like them. I have mounted my first one in my G Scale locomotive to monitor the on-board battery.
