Review: Great product and value for what it is. - I bought this product a little while ago and found it to really useful and well thought out. Here is what I mean. I have a MacBook Pro 2018, which mean the only ports I have are USB-C ports, so this product is perfect for me, however, my parents have a PC with no USB-C port, which is no problem with this product because you just have to pull the back end to reveal a USB-C to USB 3.1 adapter, and you can even connect and USB-C cable to it to transfer data too. so you have three modes of data transfer. So it was no problem transferring anything to my parents PC. extremely simple and extremely fast. Now to talk a little about the product itself: Durability: This product feels very premium in the hand, the cap is perfectly cut to fit the USB-C end without being flimsy, so you can be sure that it will not come off by accident and get lost. Actually taking the cap off and putting it back on has a very satisfying feel to it. On top of that, the cap and the body of the USB both have two small holes to attach them with string, so if you are the type of person to lose caps, that is for you. this is a product that will last for years. Value for the money: For what the product is, it's durability and convenience (having 3 ways of transferring data (by USB-C, USB-C to USB 3.1 adapter, and the possibility to get it connected to a USB-C cable), the value for what you get is absolutely amazing. Summary: if you are looking for a durable, high-end product, without spending too much money, then you found it. This product will last you years, you can be sure of that.
Review: It is a good, reliable drive - I am a programmer and use these things a lot. Most of these are very fast, but overheat and slow down. After enough over heating cycles, they just stay slow. This thing gets warm, but not overly hot like my other speed demons. I never just leave it plugged in for that reason. From a speed standpoint, it is still dialed in and flying. The little USB-A to USB-C converter is awesome since my customer machine is all USB-C and my machine is both, but my company issued Surface Laptop is all USB-A along with my many older machines, thereby making it easy to float around the fleet and transfer stuff. It feels stout, fits into the machines well, and chugs away quickly, so really there is no downside here. The only reason I didn't go for the larger drives is simply because I live in fear of losing it. I wish someone would make a way to find a stick when you lose it like a Apple tag or whatever. I would buy that drive!

*by G***B on March 23, 2020*

This is a a technical review from a technician about how I use this professionally. If that's boring just buy it. This is the best USB/A & Type C drive there is. I take side jobs fixing people's computers either at their office or their home. 99% of people are great but sometimes I want out of their space ASAP. Well, this cuts down a fresh install of Windows 10 by 15 minutes at least, vs other thumbdrives. Most recently someone was locked out and they were going to pay more if I didn't have to do a fresh install. So I needed this to add an admin user via CMD and it turned a 15 to 20 min into a 1 or 2 min job. Very very happy. I could not be happier. For the 99% of people I don't mind chit chatting with it makes them even more impressed and think I am even better than I really am. Good tools make the difference. There is enough space here that I partitioned the drive with windows 10 for fresh installs and then 2 portable versions of antivirus (depending on their free one from their ISP), a screen saver with my business info on it, portable CCleaner and EaseUS and some other settings on the other partition. If it is a customer I want to go above and beyond with I can just get all this done off the jump with no internet access and it rarely matters how good their computer is. I mean this thing is just great.
