Review: Really good for the value - The only thing I don't like about the dm303 is it didnt have a rechargeable battery. It did however come with 4 aaa batteries. Other than that. It does whats its intended to do. Testing circuits and relays is truly awesome. For the price this thing can't be beat. The oscilloscope I have not used yet but.inhave tested it. And it works can't wait to use in the field. Again best bang for the buck and look forward to future jobs to try this out on. Will update once everything has been tested.
Review: Not durable enough to have in a shop. - Great idea but it would not last long in a shop environment one drop and it would fall apart.

### ⭐ Not durable enough to have in a shop.
*by M***A on April 12, 2024*

Great idea but it would not last long in a shop environment one drop and it would fall apart.

### ⭐⭐⭐⭐⭐ Very Nice Multimeter
*by A***E on October 29, 2023*

As a professional automotive technician, an accurate digital multimeter is a commonly used and necessary tool in both my career and also at home. This digital meter comes packaged in a nice hard plastic case with a foam cut out tray to protect the meter and storage for accessories underneath it. The meter runs on 4 AAA batteries which are included as well. It comes with nice test leads and an array of test leads and cables for different component testing also. The meter has a nice, crisp, bright screen which is adjustable. The main screen when turned on gives all function options for the meter. I have really only used voltage measurement and amp draw measurement functions so far but this tool is capable of graphing and also output for relay activation's. This tool has a ton of functions and tests above and beyond an average meter. The quality is very good and it is easy to use and navigate. I give this meter 5 stars for quality and value. You will be hard pressed to find a better value for such a high performing tool.
