What Our Customers Say
A few recent 5-star reviews from verified buyers on Trustpilot, in their own words.
I did a lot of comparison shopping before purchasing a computer a few months ago. Not only does Tough Outlet have some of the best pricing, they have more customization options than other vendors. On top of that, their customer service is OUTSTANDING. When I needed another unit this week, I didn't to shop around. Tough Books will have my business always!
The cf-33 i bought from them has been a trooper for me. Laptop had no scratches, broken/cracked plastics, missing parts, nonfunctional interfaces etc. I am completely satisfied with their service and support.
Very good, reliable, sturdy PANASONIC CF53 PC and excellent service when I purchased a new, rubberized keyboard; and now when I purchased a new Windows 11 hard drive to update the PC. Brian's customer service is commendable.
Emails with Brian were sooper fast. Answered my questions rapidly and sent me a quote that i couldn't refuse which included the place order box. I've always had a ton of respect for these Toughbooks !!!!
Great price and great customer service. And shipped fast as well. Couldnt ask for more.

Toughbook CF-31 Buying Guide
Which CF-31 generation should I buy?
All six generations share the same rugged body, 13.1" touchscreen and ports. The differences are inside. The mk1 and mk2 are the budget choice for basic and legacy software. The mk3 and mk4 add USB 3.0 on Core i5 models and are the best value for everyday field work. The mk5 adds faster 802.11ac Wi-Fi, and the mk6 is the newest, with a 7th-generation Core i5, up to 32GB of DDR4 memory and a Nano-SIM slot for 4G LTE. Not sure? Ask us and we'll match a generation to your software.
What you get with a Grade A CF-31

CF-31 vs CF-30, CF-33 and TOUGHBOOK 40
