Excellent quality, solid construction! ONLY complain that I have a price! I've been looking for these caps for a long time and finally decided to stop at the circuit caps as the others just weren't suitable. I found either too cheap or these "too expensive". If they can somehow lower the price, I'm sure sales will skyrocket. (Less profit but more sales, the profit for the sellers still remains the same but is highly appreciated by a larger group of buyers)
