The quality of products received was average, meeting general expectations without outstanding features.
2021-08-06 00:00:00
Very nicely designed and manufactured. The screw terminals (used with crimp terminated wires) allow for a professional and secure installation. I will buy many more!

The quality and service of the electronic components I purchased from Jakelectronic are OK. The product performed as expected and the delivery time was not too long. The only problem is that sometimes they don't have enough stock and I have to wait longer to get the components I need.
2021-07-08 00:00:00
I appreciate the detailed product descriptions and specifications provided on their website.
2021-07-02 00:00:00
Prices are reasonable, not the cheapest but fair considering the quality of products offered.
2021-06-24 00:00:00
Very easy to use and Simple Straight portal with no Ads

The experience of buying electronic components on Jakelectronic is mediocre, and sometimes better product classification and search capabilities are needed
2021-06-19 00:00:00
All the pins and all the options in one package. Much enjoyed!
2021-06-18 00:00:00
Super easy to search and buy any electronic chips and their details.
