Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Here is a great example of customer service. I purchased the pots wanting to replace a 20kΩ pot with a 10kΩ pot. At least I think I did. BTW, no schematic. I had measured the original pot at 20kΩ. I replaced it and the circuit didn't work as intended. I measured the replacements, my DVM showed 100kΩ, and contacted the vendor. They measured their stock and found them to be in compliance. I measured mine and they weren't. Or were they? I grabbed another DVM and indeed, the pots were in spec. The original "20kΩ" pot was really 2kΩ. Aha! I really need a 1kΩ pot. And that faulty DVM goes to the recycler.
I bought three sets in 10K, 100K, and 1 Meg values. The lower valued ones are OK but the 1 Meg vary wildly between about 740 to 870 K between different pots. What’s more, the value isn’t even marked on the case which is what led me to check them in the first place. I need small pots for a crowded control panel and these otherwise would have been a good choice. I’ll either return or trash them depending on if I didn’t throw out the original box. I’d rate them 1 Star if not for the other ones being a lot closer to the right values.
The 1M pots are actually measuring around 870k, nowhere near 1M. Like another review said, they are not even marked for their value which is what led me to check. Very disappointing.
