I don't have particularly strong feelings about electronic components purchased from Jakelectronic. The quality and performance of the product are OK, there are no obvious problems, but it did not bring me a particularly big surprise.

I am a satisfied customer of jakelectronics, and I will continue to support them for their excellent service and products.
