Your bet is correct, I have seen multiple items on Amazon that are the exact same manufacture as on Ali. Rock Brothers is one of the biggies. If you want, you can read the reviews on Amazon to get a better read on quality and satisfaction. Am always leary of too good to be true prices or anything that plugs into a wall socket, so pass them by. Bought cadence and speed sensors for my other bikes which worked great with my Garmin for a fraction of the price.

I have also ordered solar motion detection lights for the house as well as soap racks for the shower, and multiple other items for the home and have only been disappointed once with quality. Forget refunds and returns though as well as a response from customer service. It is virtually impossible regardless of what they say. For less expensive items which may be disposable, I have no issue. IMO: It's a risk but for their prices its not much of one.

In that case, it would make more sense to just buy the cheap domestic stuff and avoid the chance of getting cheap crap.

It was about a year ago. Before then, I hadn't had an issue although sometimes it'd take months to get my item.

Ali is open to a lot of different sellers. Aliexpress isn't the problem, it's an issue with some of the sellers Aliexpress allows to use their site. Amazon sometimes has issues with their sellers also, but Amazon will almost always refund your money even when the actual seller won't. I recently had an issue with a seller on Amazon and got my money refunded where if I would've had the same issue on Ali, I likely would've been out of luck.
