I bought this for my better half as I've had one for about 18 months and grown to love mine. I was worried that she might have missed her precious fitbit but I had no need to worry. She loves her new Apple Watch Series 3 and has no desire to go back to not having one.

Super fast delivery of the watch. Absolutely love all the apps and features of the watch and the fitness tracking

I originally bought this product because my car doesn't have BlueTooth. The watch allows me to hit the green dot and take the call simply be holding the watch to my mouth. However, I do have one complaint; namely, the watch has so many features and accessing them is a matter of hit-or-miss.

The Apple Watch Series 2 was the answer to a question Apple had been asking since its very first wearable: What do people actually want their smartwatch to do The resounding answer was fitness, and in response the Series 2 doubled down on getting you in shape.

LTE brings new freedom; Faster performance; Call quality is very good

Additional monthly cost to have LTE; Third-party apps are lacking; The curious case of the red dot

The Apple Watch Series 3 is the best overall smartwatch you can buy, but battery limitations and add-on fees keep it from being a must-have upgrade. Apple with likely release an upgrade later this year.

Cellular connection works well for phone calls, email, Siri and messages; Music now syncs more easily; Improvements in fitness tracking and added watch faces; Adds barometer to GPS and swimproofing; Same overall size as last year’s watch.

Battery life takes a major hit when making calls or during GPS workouts; 42mm cellular model is expensive, and that’s before monthly wireless service and Apple Music fees; Still requires an iPhone to set up and pair with; A new Watch is expected later this year.

A genuine gadget marvel, but its 4G smarts just need a little longer in the tech oven

Incredibly small for a 4G smartwatch; Still the best fitness tracker around; Voice calls work surprisingly well; Battery life holds up; even when using 4G; Huge array of bands means you can make it your own

Only available on one carrier in the UK; Apple Music streaming not yet available on 4G; Not all apps work on 4G without your phone; You still need an iPhone to use it; Overkill if you mainly want fitness tracking

Great product. I like the features it has on it easy to use

Very happy with my purchase. It had proven to be very useful for recording activities and encouraging behaviour changes to move more. Suits a larger wrist as looks oversized on my partner who has smaller wrists.

The Apple Watch Series 3 is essentially a suped up Series 2 with improved battery life and performance. Apps load faster, Siri is smarter, and the sports/activity tracking features are better.

Improved battery life over Series 2; though still not that great; Large ecosystem of apps and accessories; Much faster than the Series 2; Water resistant with plenty of sport features; Very helpful smart features including notifications; music playback; and Siri

Still requires phone to be helpful (this is not the Cellular version; Expensive; Always looks like a smartwatch; Not terribly durable

The future of smartwatches is being connected, but the Apple Watch Series 3 doesn't deliver on that promise. Get the non-LTE model instead.

Improved fitness-tracking features; Faster Siri with new vocal responses; Lower price than Series 2 and LTE Series 3

Still just 18-hour battery life
