David did an amazing job saving my husband's computer. A week before my due date with our son, my…read morehusband spilled coffee on his laptop. I went to Apple and they told me it would be $1000 so we should just buy a new laptop. I thankfully then found Cosmic Computer on Google Maps and decided to seek another opinion. David was extremely kind and helpful- he took the computer apart and packaged it so I could take it home and air it out. He then put it back together, and it is working perfectly. We are extremely grateful, especially with our son's birth right around the corner. I'd highly recommend David.

Scammer. Used to bring my electronics here for several years, and all of a sudden the last laptop I…read morebrought to this place - I come back to pick it up and he tells me he returned it some company that called him and asked him to return this computer. None of this makes any sense. No notice of any kind, he did not call me to tell me this, no receipt or proof of anything! Just stole my laptop and lied about it. If you do bring anything to this place, ask for a receipt or some type of proof of drop off.

I so appreciate working with Dave and have been doing so for at least 5 years now! He knows how to…read moresolve every computer challenge I have brought to him and what I love the most is that he is able to explain what it is he is doing and if he makes a recommendation, why he is making a particular recommendation. What is also a requirement for me giving someone my business is quality and response. He, or she, has got to show up when they say they will and deliver on their promises. Dave does both, all the time. In this day and age, being able to work remotely is becoming more and more the norm. It is also critical that it is secure to do so. Dave does this with no problem. This saves both time and money! I go to Dave all the time for my computer needs and deeply appreciate him and his work ethic and knowledge. I highly recommend him, especially if you are someone who is not a computer whiz. If you are, all the better, but if you need someone who has patience, never gets flustered, and delivers, Dave is your guy. I am so glad I found you. Thank you, Dave!

Their parts are also cheaper, and they'll install it for free, unless it's something like installing a new motherboard. They can also special order stuff and have it within 2 or 3 business days. They have been reliable for the past 5 years I have been going to them for advice and help.

The downside is that he is WAAAAY out there in the Sunset, and his storefront location is pretty run down looking. Cracked glass on the front door, hasn't been vacuumed recently etc.

I truly had no idea what else to do, having exhausted my very rudimentary knowledge about how my computer actually works. i have had a couple of bad experiences at the "genius bar" (and a couple good experiences as well, to their credit), so I decided to give Danny a call after reading his excellent reviews here on Yelp. I am so glad I did! Danny was professional, knowledgeable, honest, and went above and beyond to help me with issues that were not even part of the initial problem.

He also set up better security software and fortified the protection I have so I can work more securely from home. He works on PCs too. Not just Macs as the name would imply. Highly recommended.

After very patiently helping my 94-year old Dad select a new phone case, Az checked out the phone, and we were very relieved to learn that it was only the glass screen protector that was cracked. Az replaced the cracked screen protector with a new tempered glass one, and put on the new phone case. My Dad was very happy because his phone looked brand new again! The price for everything was incredibly cheap - compared to others, and especially the Apple Store! - and Az even gave my Dad a discount because it was an older phone. Truly the best experience ever, and it only took 20 minutes! Az, you deserve more than 5 stars!!!

Not the best place…read more My phone back screen was cracked so I came here to get it replaced. It was about $200 to get the screen changed. I got it changed and came back a few days later because I dropped it. I didn't even drop it that hard and the screen still managed to crack. I had to pay again to get it replaced. When I received the phone back, they cracked my camera lens.... I confronted them and they said they didn't do that. Thankfully I took pictures prior to the service and I showed him that it wasn't cracked when I dropped it off. They eventually replaced it for free but didn't even own up to their mistake and got petty. Few months past and the screen cracked even worse. I know I shouldn't be dropping my phone but it happens. At the same time, I shouldn't have to be paying so much money for bad quality. I wouldn't come here again...

-1,000 stars for Apple. Absolutely disgraceful customer service…read more What is the point of making a Genius Bar reservation if you're still expected to wait up to an hour? Is the concept of an appointment suddenly too complicated for Apple to understand? I was there Tuesday and was told I'd be waiting two hours as a walk-in, so I did the logical thing and booked an appointment for today. I arrived early, checked in, and patiently waited while the very nice employee gathered additional information and ran diagnostics on my phone. After all that, I was left sitting there waiting, watching two people who arrived AFTER me get helped BEFORE me. When I finally brought this up to another employee and told them I was leaving, their response--or rather, their complete lack of one--was just as appalling. Not even a simple, "Let me check on this for you" or an attempt to find out what was going on. No effort to help, no concern, no attempt to make things right. They simply let me walk out the door. Apparently, customer retention and basic customer service are optional at Apple. So let me get this straight: I made an appointment, arrived early, checked in, cooperated with the diagnostic process, and waited patiently, only to be passed over by people who arrived after me. And when I finally decided I'd had enough, not a single person cared enough to even TRY to resolve the issue. Why even offer appointments if you have no intention of respecting customers' time? And what kind of customer service allows someone to leave frustrated without making even the slightest effort to help? For a company that charges premium prices and constantly markets itself as a leader in customer experience, this was an embarrassingly poor display of service. The lack of accountability was bad enough; the indifference was even worse. Apple, your customers' time matters. Your appointments should mean something, and your employees should care when things go wrong. Today, you failed on every front. Do better.
