I paid $75 to improve the print quality of my laser printer.

I researched a color issue I had on my MacBook Pro off and on for five days, trying to figure out…read morewhy I had a glitch. Called Apple and got a Bot that lead me through all the steps I had already tried myself. I knew I was getting close to a solution, but lacked the confidence to try the seemingly last step. Only one thing to do: Call Mo at CaliPhonia. In one hour of consultation plus all my notes ad observations during the week, he was able to solve the color profile glitch issue and restore my MacBook Pro to its native color profile. He is worth every penny spent for his hands-on experience and vast detective skills. This is not the first time he has bailed me out of a jam in record time so I could keep doing my job as a photographer. He is like my paramedic for my Mac, and all is well because I know I have his technical support when things go askew. I highly recommend him. If you have a glitch... GO SEE MO!

Highly recommend CaliPhonia! The owner, Moe, provides awesome customer service and really takes…read morecare of his customers. I brought my iPhone 15 Pro Max in for a screen replacement, and he hooked it up with a great quality OLED screen. The display looks and feels brand new again--super smooth, bright, and works perfectly. Moe is super professional, honest, and stands behind his work. If you need your phone fixed right, this is definitely the place to go!

I recently started a consulting firm and, for the first time in my career, I am relying on my…read morepersonal computer. Unfortunately, my computer began to slow down and became very unresponsive, which made me extremely anxious since I don't have an IT team to turn to. I found Acamar Computer Services on Yelp and decided to contact Evan based on his excellent reviews. Everything I read was accurate! After explaining the urgency of my situation, Evan was able to see me that afternoon. During the consultation, I mentioned that I was prepared to hear that I needed to buy a new computer, considering I had purchased mine in 2021. However, after just a few minutes, Evan informed me that my hardware was in good condition. He only needed to address the "software bloat" to get my computer back in order. He also assured me that once this was done, I would likely have another two years before needing to worry about replacing my computer. We spoke on a Friday, and he kindly asked if I needed my computer back over the weekend or if I was okay leaving it for him to start working on it the following Monday afternoon. I chose to wait until Monday so I could finish a few more tasks. I dropped off my computer on Monday evening and picked it up the next day. Evan took the time to explain in detail everything he had done and how each change improved my computer. Evan is extremely talented, efficient, and a pleasure to work with. His pricing is very competitive and well worth every dollar spent. His primary focus is on delivering exceptional customer service, which is exactly what Acamar provides. I informed Evan that he is now part of "The Chrysalys Team" and will be my go-to IT professional for all my computer needs moving forward. I cannot recommend Acamar highly enough. Evan is a lifesaver!

I had completely disassembled my $400 HP printer, put it back together and something went wrong and the screen wouldn't light up. They're not only found the tiny wire inside a very, very small cable that I have broken, they showed me a picture of it and gave me a complete tutorial. then they went on to explain why my printer wasn't working anymore. It had smeared printing because over five years, I've been using aftermarket toner on an HP printer. I then asked for a recommendation on a high volume printer for home use. That's in between category between home desktop and large office printers. They said they didn't know but they researched it and called me back a couple of days later with really excellent advice I took and purchased the printer they recommended! Then one day I was nearby installed a large projection system and didn't have a long enough power cable. I went in and explained and they gave me a 10 foot power cable for free. But most important these people are are very friendly as well as mean technical experts... But very humble about it and they really listen care about the customers. Wow!

Danville Computers was the first one to reply in minutes! I waited for other quotes to come in. Danville Computers reached out again to check if I had any questions. I picked them because they could do the job and were nearby. I am very glad to have chosen them because not only was it conveniently located (between my work and home), but the service was great! Fast and efficient. Chase is knowledgeable and professional, yet also friendly and approachable. I explained to Chase what I needed - retrieve my data from my external HD. He assured me that if he couldn't retrieve it, we still had other options. Phew! I am so thankful that my data was found! I had a couple of snags with retrieving my data when I brought my equipment home but Chase was still available to help me make sure I could retrieve and save them safely. Quote was high - and even higher if my drive was damaged. I expected it to be expensive. It took 1-1/2 days which was quicker than I thought it would be. I appreciate that Chase was still available to help me remotely with no extra charge. Thank you!!

When we got the new power cord and it didn't work either, we quickly realized we needed help getting the files off the hard drive of the dead laptop. We hadn't had a chance to backup the files before it died. We put out a project request on Yelp and started looking for companies that could help us We found Fastball Computers and Scott Nelson. Scott responded to our phone call and project request and was able to see us the next day at his shop. We took our laptop and got to watch Scott take out the hard drive and connect it to his computer and then transfer our files to our external hard drive. Scott knows his stuff and explains things so you understand what he is doing. His price was incredibly reasonable for the work he did. We have new laptop for my wife and all her files and pictures and are able to move forward. If you need data recovery services or other computer services, don't hesitate to call Scott. It's nice to have a company near us when we need it.
