SP Electron Multifunction Dual LED AC/DC Light Tester Pen (Pack of 1)

I have used this product to detect live in rains, it has worked excellent

I recently purchased the SP Electron Multifunction Dual LED AC-DC Light Tester Pen, and while the build quality is good, it doesn't quite meet my expectations in terms of functionality.Build Quality:The tester pen is well-built and feels sturdy. The design is compact, and the LED lights are bright and easy to see, making it convenient to use in various settings.Functionality:However, when it comes to testing, both sides of the pen give the same result, making it difficult to properly test AC and DC currents. This limitation reduces its overall usefulness, especially for someone who needs to differentiate between the two. It's disappointing because I expected it to accurately detect and distinguish between AC and DC currents, but the tester doesn’t seem to function as intended in this aspect.Value for Money:The product is reasonably priced, and while the quality is good, the lack of accurate functionality limits its overall value. It may be useful for basic tasks, but for anyone needing precise testing, this product may not be sufficient.Pros:Good build quality and sturdy design.Bright, visible LED lights.Compact and easy to carry.Cons:Unable to accurately differentiate between AC and DC currents.Both sides give the same result, limiting its functionality.Recommendation:If you're looking for a basic light tester pen, this product might work for you. However, for more precise electrical testing, it may fall short of expectations.
