Some weeks ago, I purchased 100 X 470uF 25Volt electros. WES part number: 470WLR25. Wehn I pulled a couple from the bag, I noticed some blcak fluid on some of the caps. I eventually found 15 faulty caps. All were showing leakage from the top of the cap. A phone call to WES elicited both an excellent response and a truly disturbing response.
Response #1 (from a sales monkey):
"It's ONLY 15 out of 100."
YIKES! I then demanded to speak to a human.
His response:
"Very sorry sir. That batch was faulty. Just throw them out and we will send a new batch to you today."
If anyone has purchased these caps in the past three months, be careful. I certainly won't be using any of them. Even the ones that appear to be OK.
