My thoughts as well.
The website is safe to use. The app seems like spyware.
Additionally, I would be very hesitant about ordering anything expensive, anything that plugs into an outlet, or anything with moving parts you use for food.
Most of the things I've ordered on there are cheap little trinkets. I got some solar lights, some windchimes (excellent for the price - I paid like $3, same thing would have been $20+ on Amazon), etc.
One time I ordered this little non-electric hand blender - like a whisk that you when you press down on it, the whisk part spins and mixes. I ran it through the dishwasher before I used it... so glad I did. All kinds of brown gunk came out from inside of it and seemed to keep coming. I threw it out. I only paid like $1 for it.
I did get some silicon air fryer baskets for like $1 each, and some silicon bread pans for $2 each. Well worth it.
So it's hit and miss.
I've seen ads for bigger things - even one for a garden shed! lol! I would not buy anything like that from them.
