I received technical certification with a good staff. They have good fair prices on brand names.


July 11, 2020

I always have good experiences in dealing with Heisener Electronics. They have the components I need in stock, their search function is great, and shipping is fast and always as promised.


June 24, 2020

Great kit, cost half the price of other stores. Includes most items that someone would need.


June 23, 2020

Very good product for electronic projects and are of great quality and test great.


June 17, 2020

Outstanding supplier! Heisener is on a very short list of suppliers I can recommend. From stock, pricing, ease of ordering and great service, they get it all.


June 16, 2020

Worked very well! I would highly recommend buying.

June 16, 2020

You're my good supplier. I appreciate Heisener Electronics on many levels.


June 11, 2020

I recently became very interested in electronics and I have used several of them. They work great.


June 7, 2020

I've made a few purchases from Heisener and always get a friendly technician helped me with locate what I was looking for. That kind of attitude is greatly appreciated.


June 2, 2020

Work Great. Would recommend. Only used 2. So I have 248 extras. Best deal by far that's why I got these.
