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!
2021-07-08 00:00:00
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
2021-06-19 00:00:00
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.
2021-06-15 00:00:00
great value for price.
