I have bought a second phone from them, and it has been very easy. They come in excellent condition. I recommend them if you ever want to buy a phone.

I bought a iPhone from Tech Exchange on the 26 February 2026 and received it the 4 March, and the service was absolutely amazing. Richard contacted me and just offered me different options on the phone I wanted. Absolutely amazing service and will definitely recommend them. Thank you for the excellent service. Regards Yolande

Outstanding experience – highly recommended

I was honestly quite skeptical about buying a refurbished phone, but my experience with TechExchange has completely changed my view.

The phone arrived quickly, well packaged, and in immaculate condition — genuinely looks and feels brand new. Screen, body, and overall finish are flawless, and the device performs exactly as it should. If it hadn’t come in a refurbished box, I would have assumed it was new.

Communication was clear and professional, and Richard at TechExchange was upfront and helpful throughout the process, which I really appreciated. Delivery was fast, and the whole experience was smooth from start to finish.

What really stands out is the quality of the refurbishment and the confidence they inspire. It’s clear that these devices are properly checked and graded, not just resold.

I’d happily recommend TechExchange to anyone considering a refurbished device, especially if you’re on the fence like I was. Great service, great value, and multiple payment options make the whole experience even better.

Will definitely use them again.

Excellent service. I was reffered to your company and made my first purchase. I was informed that there would be a color change on the device as the initial one I ordered is faulty. They asked for my consent and I agreed and within 24hrs my Demo IPhone 14 Pro Max was delivered to me. You guys are the best.

If you are looking for a credible, reliable and professional company, who goes over and beyond, then Techexchange is most definitely a brilliant option.

After a different online company stole 13k from me, I was obviously nervous about placing another order.
I emailed them and explained that I was apprehensive to order anything online anymore due to my experience a few days earlier.

Within minutes I received a phone call from one of the friendliest and most professional people, who spoke me through the process and asked for more details of exactly what I was looking for.
He then checked to ensure availability and spec of the device and stayed in direct contact with me, updating me constantly.
This was not just an employee, but the CEO.

Richard, THANK YOU.
Your company delivers on exactly what you offer, in service, spec of goods and standard.
It is absolutely awesome to work with a company with such high integrity and professionalism.

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!

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.

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.

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

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.
