    Great people to work with quick to respond to my issues quick to take care of the issue. Great shipping value is probably right on just solid people. I recommend them highly if you ever have an issue, they would take care of it immediately I’m not saying that have issues or anything I’m just saying if you had one come up. I would recommend buying from them anytime.

    Great customer service, quick to answer and offer help. They ran out of stock and supply was late but nothing the seller could impact. Offered a discount so I am very satisfied, can recommend seller👍🏻 Postage cost is determined by eBay international shipping and not seller, so all in all good deal and good price compared to others.

    Boat Maintenance works fine

    My usage is for a boat and the ability for the DC Amps is wonderful. The reason of my purchase of this model is the DC Amps NOT just AC. The ability to check the amps being drawn when starting or checking the boats equipment is very helpful. It is NOT a replacement for a shunt/battery monitor on a boat but it does help in checking the draw on specific devices. The other features are nice but I haven't gotten full use to these. I am still using my other meters for those needs. Over time I am sure that this will support all of my usage for the boat maintenance. I am NOT on salt water so I cant speak for how long it will last in that environment but am hoping that it will stay functional for many years to come being stored at the lake. Most devices last only to find the batteries ...

    Any One that knows how to use a meter would be very pleased with this meters performance...

    Compared to a Fluke Amp Meter of same meter Ranges.... It has far more to offer... Non-Contact voltage sense... temperature probe... Capacitance setting and DC amps as well... Price compared this meter wins hands down... I wish it were Cat IV and IP 67... but for the average tech or savvy electronics person... a must for the home shop at this price...

    Best Bang for the Buck

    Southwire products are great values for the money. I've used Flukes and still have a few, even the 88. But they are generally 2-3 times more expensive and, for the most part, I reach for my Southwire. I also have their cable tester which is outstanding.

    its capability of measuring milliamps and volts accurately is questionable.

    If you want to really measure in Milliamps, then due to the significant figure of digits, I doubt it will suffice. Find another product.
