OnePlus7 purchase
Having never used OnBuy before I was a little nervous. The independent online reviews for OnBuy helped distance some of the worries. Great service in terms of placing an order and tracking. Received tracking information once the order was shipped. I actually received the order… read more

Legitimate Oneplus Device

Real 1+ device, came in mint condition in original packaging. Plug in box is US 2-pin, but a UK travel adapter is provided. Fantastic phone at a bargain price!

shame on 1+ for not providing earphones though...

Excellent phone

This is a top drawer phone and I love it. Great size, love the feel of it, especially the touchscreen. Super clear display screen and sound quality is super too. Came with a clear protective case and this was an unexpected bonus. Not at all heavy. I love it!

Very happy

Delivery in 8 days. Updated to Android 10. Extremely fast phone. Installing apps especially small ones instantly. Opening apps like all of them are in Ram.

Great phone

Amazing phone, the first android having switched from iPhone and I'm more than impressed. Top phone with a decent camera and a great all-rounder. At this rate, my next phone will likely be a OnePlus too.

Awesome Phone, great buy

My first order from OnBuy and also my first significant purchase from a reselling site like this (as opposed to a national retailer). I couldn't be more satisfied. The phone arrived in perfect condition, rand new and working - it is fully ready for the Uk and I had it set up and making calls in less than 20 minutes. The OnePlus UI is really good and the Android wireless smart transfer meant i could copy all my data, settings and contacts really easily. I would definitely recommend buying this phone through this site - it was half the price you would have to pay in the UK and the delivery time was very good

Great priced flagship

The specs of the phone are much better than the price would indicate, a great value flagship phone that should be considered as an alternative to the bigger brands.

Great experience

Bought this brand new phone online, contacted customer ser a couple of times before ordering to clarify a few things. They were quick to respond and gave me the answers I needed. The phone arrived quickly and tracking was available throughout the delivery process. Will use OnBuy again, very happy with my purchase.

Great value

The phone arrived over a week early. Incredibly good value for a brand new phone. I'm very happy with it so far.
