Mastech MS8268 Digital Auto Ranging Multimeter

Mastech MS8268 Digital Multimeter

At an extremely cheap price – you’ll find the Mastech MS8268 Multimeter.

While it’s cheaper, the Mastech multimeter simply isn’t as capable as the Klein Tools MM400 – which will provide you with better value for money (even if it’s a little more expensive).

For example, the Mastech digital multimeter is slower than a lot of competing tools. It takes a little longer to get a solid reading – and that time can add up.

The 15-minute auto-shutoff feature is also annoying, and it can interrupt you while you’re in the middle of a job.

Although the Greenlee DM-45 Multimeter falls short of expectations, particularly in terms of lead quality and display clarity, it serves as a cautionary reminder of the importance of choosing quality over price alone.

This model is full of problems that honestly shouldn’t exist at this price point.

Let’s start with the test leads: they suck. They are way too short for comfortable use, and just scream “low-quality”. They were clearly NOT built to last. If you end up buying this multimeter, get yourself a good replacement extra long multimeter test leads.

Greenlee DM-45 Digital Multimeter Home Use

The display is also unusable. Not only does it lack a backlight making it impossible to use at night – but it’s even hard to see during the day!

If all of this wasn’t enough, the three-minute auto-off timer combined with the relatively long startup time will drive you insane.

Not worth it – even for home use. Skip it.
