I am coming from a Venu 2 and the Venu 4 is a real step forward.

After five years of the Apple Watch SE 41mm, it was time for a new smartwatch. Because I had to charge my Apple Watch every day, I was looking for a smartwatch with a longer battery life. That's why I chose Garmin, and I definitely don't regret it! I chose between the Vivoactive and the Venu 4, ultimately choosing the latter for its design and extra features. The Venu 4 also looks much sleeker than the Vivoactive. I opted for the 45mm version. It fits nicely on my wrist (18mm). It feels more comfortable than the Apple Watch. I've had it for a week now and haven't used all the features yet, but I'm very happy with this purchase.

I purchased this Garmin Venu 4 (45 mm) to replace my old Samsung Watch 4.
I certainly don't have thick wrists, but this 45 mm version fits perfectly and isn't heavy on the wrist. The watch has a huge number of features that I will never use all of. I am purely interested in the basic functionalities such as paying via Garmin Pay, reading navigation messages, and so on.
Unlike my old watch (1 day), the battery now lasts 12 days, which is much more pleasant.
Also handy is the flashlight function, which is easy to operate with the push of a button and provides a lot of light; I really hadn't expected that. You can adjust the brightness and even make it glow red to stand out in the dark. It takes a little getting used to how everything works at first, but once you figure it out, it's a breath of fresh air that I will enjoy a lot.
In short, a good purchase and value for money.
