The most important thing in modern handheld DMM is CAT safety since the features sets and accuracy are well established in the low cost price range, about 0.5-1% for all the ranges.
By insuring it meets all the regulations for safety by the IEC, it will coincidentally mean the device is well made. Quality has deteriorated a lot on the low end of the DMMs, particularly no name Chinese models, so up front they look like they work, but its only when things go wrong or it becomes inaccurate some months later, that its too late to return it.
FWIW by comparison, the same features in non-CAT safety rated DMM can be had as low as $3, from Harbor Freight. They almost universally do not have a 3rd party certification, so avoid those that have only the nearly useless CE mark.Certifying bodies for safety are UL, ETL, TUV or similar. A lot of IEC regulations up the cost, but it has separated the workable, safety made and durable DMM from the chaff.
Consider Extech MN15A or something similar by Amprobe or Greenlee. Avoid no name brands; even Sear brand could be a relabeled Extech of even a low cost Fluke, but you never know. Buy one from a maker of testing gear, that's all they do so chances are they do it better.

The lower cost $20 MN 35 is very similar, but not certified and slightly smaller LCD screen.

If you've ever been to a doctor's office, I don't think saving the $5 is worth the risk, even if its small.
