Many smart watches now include a blood pressure sensor and some even measure your oxygen saturation like real oximeters.

But how do these cheap watches compare with FDA-approved devices?

This is the first part where I try a watch claiming to monitor the SpO2 level (Oxygen saturation level)

The CMS50D+ is a pulse oximeter with qualities essential for the detection of sleep apnea and the ongoing monitoring whenever the condition has been already medically confirmed.

Some particularities not available in most devices of that size make this particular model unique.

The latest OTA V2.0_20180815_20181113-0939 from Umidigi resolved the serious bug whereas non-system apps would not auto-launch at start up.

This, in turn, prevented notifications to appear from messaging apps such as Hangouts, WhatsApp, Viber, ...

The Umi One Pro is now working as a normal communication device!

This is a short list of some my favorite inexpensive gadgets that could make cool gifts  for friends and family (or better, for yourself, because you know you deserved it!).

I spent a few weeks using the Umidigi One Pro before posting a review.



This phone caught my attention with its generous specification: FullSurface 19:9 notch display, dual cameras, 64GB ROM, NFC, fingerprint sensor, wireless and fast charging for less than 150€/170$.

Is it too good to be true?

I several a wireless headphones over time and found none of them really convincing, either by their sound quality, or by their design.

I might have just found the type that works for me.

The H1 Air Mouse is another inexpensive remote controller.

The large touch-sensitive surface on the reverse side can be used either as a keyboard or as a touch pad.

This remote is absolutely fine, but you must use caution when purchasing it.

The Alfawise V2 is a great mechanical keyboard with many RGB modes and assignable macro keys.

While most functions are available via the keyboard itself, its companion software is useful to reveal its full potential.

Mecool KM8 is a Google Certified Android TV box that supports Google cast, 4K playback and Voice control.

It's currently in flash sales at Gearbest for $59.99/€51.90 (Coupon Code in the review )

The Xiaomi Redmi S2 (also known as Redmi Y2 in India) has many points in common with the Redmi Note 5A (also known as Redmi Y1 in India...).

Like the Redmi Note 5A before, it is another affordable entry level smartphone built around strong cameras...but offering an even better value for the same price.
