I have been used Kristina with Boxaid many times and she is extremely proficient at her job! She really is a lifesaver. I wrote a review of Boxaid and Kristina in 2018 on Yelp and gave her out of 1 to 10 a 15! I had to buy a new computer to go from Windows 7 to Windows 10. I couldn't upgrade my old computer. It was out of date. She, as usual, did a stellar job and set my computer up perfectly... just like I asked her to. I will use Kristina anytime I need computer repairs.
