I wouldn’t trust anything with a price point so much lower than Garmin’s. A used watch at that price might be worth the risk, provided the seller has a good reputation. Craig’s List might have something.
if you can find someone with a Vitality life insurance policy - they get the 5 series at 40% discount from Garmin - probably the best discount to be had that has no risk factor.
Yes I've used Eglobal Central by accident... I thought it was a UK company, as their web page is confusing but legal. Anyway I bought a Casio Rangeman, normally at the time over £300, but I only payed £170. Then saw the small print Chinese company. So I nervously awaited its possible arrival? Watch arrived, all correct was European model very luckily for me. ::::::::::::::::::::::: The problem is the guarantee, its with Eglobal Central not Casio, meaning you have to send the watch back to China at your own cost for them to maybe receive it,maybe fix or replace etc... So I couldn't recommend them for a more technical Garmin watch where you might need support. All the best...
I've also bought my Fenix 5S from Eglobal central. No issues what so ever. Very cheap (€379 for a black Fenix 5S). I dit pay with paypall to be sure I would'nt lose my money. But like I said; everything was perfect. No hassle with duty/taxes. Shipping updates where given nicely. Took about a week to get it (live in Holland). Since they've got a warehouse in the UK I think it would arrive sooner in the UK itself.
