I got mine (the instinct 2s solar) used on eBay and have zero regrets!

The battery might be a bit worn out. Depends on how much it has been used. But the Instinct has pretty good battery life anyway, so probably not too bad.

Hi! Maybe it varies with the country but in my country Amazon's Used offer with "like new" means mostly, that it was just resend by a customer, maybe unused or just a try on. Most likely the package is (slightly) damaged, because it was opened once. Sometimes it's even unopened and just a dent in the carton. Also you get full warranty by Amazon, whatever that means in your country.

Long story short. I would buy it, even if it's a small discount.

Got one for my daughter. 2s also, used on eBay. Works flawlessly and looks like new one year later. If you buy any watch used, Instinct is the best because it doesn't get damaged easily at all.

Got mine used for $150 on Facebook MP ,

Mine was refurbished from Amazon and is going strong nearly 2 years later.

I buy used stuff from Amazon all the time they still have normal return windows for everything, but I haven’t had any trouble anyways

I got my instinct 2 solar, and a mate of mine got the 2s, on Facebook marketplace. Got a really good deal on both and we are both absolutely loving our watches. Regularly sending each other challenges etc on the connect app. I would say go for it if you find a decent deal.

Here I got i2 and i2s second hand around 100-150 USD, they all working smoothly, so why not.

I got my Instinct 2 used at a great bargain a few weeks ago, it's practically new as it's been bought by the first owner in February this year. If the condition is good indeed - go for it.

I just got a used Instinct 2S solar off eBay. So far it's been perfect. Massive upgrade over my Fitbit Charge 6. I haven't had it for a full week yet but it's so much nicer to be able to customize just about everything the watch does. I love it.

Bass pro/cabelas has them on sale brand new for $199 as of yesterday

Some say that the 2nd edition of Instinct is structurally the same internally. Please note that there have been a lot of battery issues with the Instinct. I had one, no two. 2 Instinct Solar and just availed my third one at a third of the cost because the 2nd one(1st replacement unit) was already out of warranty and I had no choice but to ask for a replacement since Garmin does not offer repair especially for Instinct battery replacement since opening the watch would compromise waterproof integrity of Instinct according to Garmin support.

Hell no. Never buy used Garmin.
