I encourage everyone to read 's review of the OnePlus Open to learn everything the phone offers. However, if you'd like a quick summary, you should first know that the device remains one of the best foldables on the market nearly two years after its release.

Review: OnePlus Open

Its vibrant AMOLED displays, high-end performance, and durable design make putting down the OnePlus a herculean task. Open Canvas is a key feature that makes multitasking a breeze. It allows users to place multiple apps side by side for easy access. 

For example, you could combine two shopping platforms and compare product prices, or have Google Maps next to WhatsApp when planning a date.

We've also reviewed the OnePlus Watch 2. Contributing Writer Matthew Miller praises the device, calling it "one of the most perfectly designed pieces of smartwatch hardware." It addresses all the problems the original wearable had while adding a battery capable of lasting days on a single charge.

How I rated this deal

As per 's rating system, I give this deal a score of 2/5. If you participate in the recycling program,$200 off the OnePlus Open is an 11% discount, which is small, but you do still get a free smartwatch. Putting the two together bumps this deal to a 3/5 since you'll save$500.
