Great Buy
Style: Type C/G/A-Most Countries-3FT
Bought for trip to Italy. The long cord worked great as I had several things to charge and the side tables weren't big enough. This reached the floor and nothing was falling off tables. The plug fit snugly in the socket which was key as they tend to be loose there. Don't take your own hair dryer or curling iron, they burn out from the amperage there.

Fantastic adapter for international travel
Style: Type C/G/A-Most Countries-3FT
This adapter worked as intended when needing to charge devices in Europe. The adapter was easy to attach to the plug and the cord length came in handy for sockets that were in hard to reach locations. The only thing is it does take up some space in luggage, so make sure to account for that. Would definitely recommend for international travel.

Stunning Automatic Watch With TopTier Durability and Precision
Color: Grey
“I got this Tissot PRX for my cousin’s birthday and bro fell in LOVE instantly. This thing keeps time like a beast, never slows down, never lags. Automatic movement, so no batteries, no drama. Durability? Stupid good. You can hit it, bump it, live life rough, it still looks box fresh. Size wise it was almost perfect. I just had to remove two links, nothing big. It’s light, functional, comfortable, doesn’t weigh you down, doesn’t get in the way but more importantly I can say this watch is in everyone’s eyesight when we wear it. Cause of course I had to get another one! Basically. I gave him a very nice piece as a gift, and now he’s walking around like he owns Switzerland.
