Great for keeping an eye on the condition of your vehicle battery and alternator.
The product is well thought out, well made and very easy to use. It has a clear display and the flexible elbow between the display and the plug makes it easy to set up in an easily viewed position in the cigar lighter/aux socket. Shipping is a bit expensive if you live in the UK, but I think the product is worth the extra expense. Glad I bought it.Verified purchase: YesCondition: New

Peace of mind
Very satisfied to have an accurate digital display of the auto battery and charging system. I keep it connected at all times. The soft green display is very visible at night allowing me to check at a quick glance to know all is well. Immediately after turning on ignition before starting motor I can see the voltage in the battery allowing me to see if the battery is in top performance and has retained its charge. Have one for both cars. Highly recommend this inexpensive but necessary item.Verified purchase: YesCondition: New

Alternator monitor
I just replaced my alternator twice, and wanted to have something to plug in to see how it's doing. I don't need a 100% accurate $90.00 meter to do this. Just wanted something well within range. This is top of all the other ones I saw, and read about. Also I can see how my battery is doing with the car off to verify the proper charge. All for my car audio needs. Running 1800 watts. Great budget meter. The plastic is of good quality, and the pivot is great for having a good view range.Verified purchase: YesCondition: New

Works great for voltage readings.
Works great for telling you what the battery voltage is to a hundredth of a volt. My trolling motor has two 12 volt batteries which I can choose to use together in parallel or either one separately by using a battery switch. This volt meter helps me to know when to switch batteries before I run a battery down so much I damage it.Verified purchase: YesCondition: New

Not a bad unit!
Quick delivery and easy to use. Seems to be fairly accurate and seems to work fine. So far so good. My car tells me what the voltage is and the 3721 seems accurate. I really bought it to check my alternator.Verified purchase: YesCondition: New
