5 stars are not even enough to describe how Happy I am... Definitely gonna make another purchase they are loving kind people who give nothing but 1100%. I am happy with my purchase.

I wasn't sure about this company, but checked out some reviews and took a chance. It took 5 working days before I held my new phone in my hand.

After nearly 6 years of owning an S10 (still a great phone by the way), I have now upgraded to an S21. While is has many of the same features as the S10, there are differences. The photos? Wow! Again, same 12 MP camera as the S10, but it does portrait-type shots even when it's on normal camera mode. I sometimes struggled to take wide shots with the S10 and get the blurry background effect, whereas this phone does it without even breaking a circuit.

But I digress, back to TechExchange. The generic charger isn't fast charging, despite what the box says, but the phone is exactly as advertised and that is definitely what will make me buy from you guys again (hubby needs a new phone so I will be back). Thank you!

Highly recommended. I bought a demo S22 then we changed to a S22 plus as my wife wanted a bigger screen
Even with the exchange all went well.
Phone is as new demo model.

I bought an iPhone 13 Pro demo on techexchange. I was extremely worried about scams but I chatted to Richard on WhatsApp who replied to all my questions. I received a call from Richard as the phone color I wanted did not have 100% battery life and he proposed me another color. I received the phone as described, new condition, 100% battery in its original box with charger and pin 3 days after the call. The courrier guy has a tracking system which allows you to follow the delivery process. I am extremely satisfied by the product and service. I definitely recommend!

i’ve bought two demo phones from techexchange two tears apart and they both appeared to be brand new. screens were unscratched, and not like when someone tells you it looks new, i mean literally no scratches. rest of the phone also great, even had those little plastic strips on the sides and the one on the screen and the back. also, the prices are great. :)

I was seeking to buy a phone. Went online and came across TechExchange,with a huge amount of skeptism, did some research and with the help of the reviews of others, I trusted the process. And here I am typing this review from my new device. Thanks to Richard and his team delivering excellent service, device was received within a day. Extremely chuffed. Thanks again.

I purchased a Samsung Galaxy S8 in May of 2024 in pristine condition and am still using it. Today, I received a Samsung A50 for my husband, and he is thrilled with it. I highly recommend TechExchange; their services are excellent, and the team maintains constant communication from the moment an order is placed until it is received. Kudos to the TechExchange team.

This is the second time we have done business with TechExchange and again, the service we received was fantastic. They were eager to help and answer all our questions. We were in a rush to get the Samsung note 9 and Richard was very kind in assisting. We received the phone in one day.

Thank you and we will definitely do business again in the future.

08:58 20 Jun 24

TechExhange's personnel are competent and friendly. Their service is excellent. This is the company that should be on top of your list. I am very satisfied with both the phone and Richard's competence and friendliness. Will definitely recommend them to my friends.

I also bought my cellphone through TechExchange, I have received efficacy customer service from Richard and that was 3 years ago. Yes at first I was skeptical however Everything was smooth, and fast from ordering to delivering. I can definitely recommend anyone to purchase from them.

I purchased Samsung A30s Demo in 2021 November. Firstly I received best selling experience from Richard. When I had a problem that phone was locked, he was ready to send a courier guy to take my phone and replace it, but my brother managed to unlock it for me so I did not need to return it. I have my phone since then working perfectly.

I ordered a smartphone on Saturday and my order was processed and shipped on Monday. It arrived expeditiously on Tuesday in excellent working order.
I am extremely happy with my speedy service and experience and I highly recommend TechExchange.

Wow wow wow, I thought nothing could come close to Takealot when it comes to smooth and seemless online shopping . I was wrong, TechExchange is even smoother and probably better, I bought a Galaxy Note 20 Ultra this Monday (10 July 2023) Techexchange was communicating throughout the whole waiting process and the delivery was the smoothest, can't wait to buy another phone for my wife from you guys, and I'll definitely be referring everyone to you guys I have been WOWED. Keep it up 5/5

What a pleasure to still be able to deal with good honest people. My business with TechExchange was rather complicated, mainly my own doing but Richard went out of his way to make it work - very much to my benefit in the end. Thank you.

I bought a new IPhone from TechExchange recently. Firstly was the price of the phone substantially less than the iStore prices. The process to buy, pay and receive it was effortless. The phone was delivered within 3 business days. I was kept informed of the process daily until I received it. Delivery was done by Mr Courier basically to my door. Very impressed with this service and I highly recommend them. Well done.

Perfect, Awesome and Flawless service form TechExchange. Very prompt on delivery and i got all the items as per my purchase.
Richard and the team at the warehouse pulled through for me. My old phone had died out, i had a trip coming up the very same day of delivery and the delivery was made early morning.

I am grateful.

The communication is top tier if not number one...i mean. Happy chappy here with a brand new phone cant even tell its pre-owned unless i tell :-)

I feel like 5 stars aren't enough to describe the excellent service I received from Tech Exchange (Richard). I bought a CPO phone from them yesterday Monday and I received in the next day (Tuesday) in literally less than 24 hours and I'm all the way in Cape Town! Exceptional service is guaranteed from them. Just like anyone, I was a bit skeptical about purchasing from them as I am in a different city however I'm glad I made this decision of buying from them. The phone doesn't even look used at all. It is scratch free and has a great battery life. I am really happy with my purchase and will be buying from them again.
