I was excited to get an iWatch for Christmas, when I got the item I went to add the cellular and was told by my carrier it was "blacklisted" and already activated by T-Mobile (I have Sprint). They said they can't activate due to being reported as lost or stolen...what the.....

We've been fans of the Apple Watch since the very first version, but most people are not like us. And this is a product line that's needed to work hard at broadening its appeal.

In terms of fitness this watch lacks what the Fitbit charge HR 2 can provide, in order to display simple fitness data you need to purchase additional apps to work with the watch. The watch also has to be charged on a daily basis, yet a Fitbit can last 3-4 days.

I got this as a Christmas present and from what I have been told the watch is amazing with all the features and clean look

I am of two minds on the Apple Watch. On one hand, I think that it's the best overall smartwatch you can currently buy. And to that end, the Series 4 is the best Apple Watch to date. After wearing one for months, it's worked really well.

The Apple Watch Series 4 offers a larger, crisp display that shows more with less bezel, super fast speed and a louder speaker; It adds high and low heart-rate detection, fall detection with SOS trigger and an FDA-cleared ECG app for more detailed heart readings

Starting prices are higher than last year; Battery life still won't last past two days; Watch face options are still very limited in choice and function; It only works with iPhones

The greatest Apple product comeback story of the past few years has, without a doubt, been the Apple Watch. Launched with great fanfare four years ago , the initial version tried to do way too much with way too little , and it had confusing software to boot.

Great battery life; Huge; beautiful screen; Health-tracking features; not just fitness

Siri is still unreliable; No always-on screen option; Complication options can be confusing

Reasonable price and friendly staff and good timing on postage

The Apple Watch keeps steaming on, and while its rivals try to make sense of the smartwatch form-factor, the Series 4 arrives with the market wrapped around its little finger. Yet the Apple Watch Series 4 is the company's biggest change since the original Apple Watch landed in 2014.

Better design; Lifesaving metrics; Top sports features

More expensive; Battery life still short; Siri integration still not great

Has there been a learning experience for Apple quite like the Apple Watch Back when the original model launched in 2015, there was – not unfairly – a sense that Apple itself wasn't quite sure what exactly it should do.

Mesmerizing new display; Fast and smooth performance; Health features could be game-changers; Battery life hasn't suffered

Siri still falls short; Expensive

When Apple first introduced the Apple Watch way back in 2015, it wowed, but was also a major disappointment for some consumers the world over. This was a rare instance when an Apple product had polarising opinions across the board. At the time, people did not know what to exactly do with it.
