ERP 4750 Microwave Diagnostic Tool Review

I use it to check around the house. Customers like to see it glow. Works great, very bright. Whole microwave glows bright orange.

We use these tools in our work and when the customer is watching it always seems like magic. I've never had cracks, but I lose them because they're crispy and blend into the countertop.

I use this to make sure the microwaves are working in the homes I'm reviewing. Works great. Of course, the water in the cup also gets hot, but it's nice to see the oven heating up constantly.

Very old microwave - part of a combination microwave and conventional oven and the microwave didn't seem to work very well. This device has proven to be good enough that it can be repaired instead of spending $3,000 on a brand new device. The picture shows the thing flashing as it goes into the oven.

This product is exactly what I expected but you still need to put a cup of water or a damp paper towel in the microwave to test the microwave to make it a cool, light toy I used Impress little kids by looking around the houses.

Looked great at first, loved it. Works well on my home inspections. However, this did not last. I put it in the microwave and suddenly it burst, made a loud noise and stopped working. You could see the burn mark in one of the colored lights. Was in the microwave no more than 5 seconds. Enough time to add an image. There was a burning smell in the room. I would not recommend it.

This device should have come with a download, not instructions on how to add a cup of water. A cup of water might have worked for my purposes without this tool, but I wanted to quickly verify that the microwave worked without taking out a cup of water and heating it. I asked someone to sew a small bag of rice on the Magic Lights tool. Now the tool is ready. It's neat, it works, but it's not a complete tool, hence only 4 stars.
