Jackson
The quality of products received was average, meeting general expectations without outstanding features.
Ringwald
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!
Angalee
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.
Marsland
I appreciate the detailed product descriptions and specifications provided on their website.
Biden
Prices are reasonable, not the cheapest but fair considering the quality of products offered.
karen
