MJ Systems

Networking Equipment Wholesaler Since 1992.


How do you decide where to buy online? Are you tired of websites with flashy front ends, that when you look more deeply don't have an address or a phone number for the company? All you get is an email addresss, yet they want you to pay them in advance by PayPal or give them your credit card number. If you give them an order, they often go out and buy the products you ordered from someone else who has stock, and drop ships for them. And if something goes wrong their virtual presence evaporates.

MJ Systems: Real Service, Genuine Products, In Stock

  1. When you call MJ Systems, live people answer. No phone trees, just knowledgeable sales reps who actually answer the phone and are happy to talk to you.
  2. Our products are all new retail equipment. Smartnet or Care Pack Ready. No used or refurbished items that leave you in the lurch when it comes to support.
  3. We have our own warehouse. All listed stock is in-house and available for shipping immediately. We are a wholesaler who also has a web presence. Clicks and bricks, not a fly-by-night drop shipper.
