Great build quality and faster than expected
I was really impressed with the overall quality of this device. It feels solid, premium, and well-made right out of the box. I used it to back up data from my mobile phone, and the file transfer speed was faster than I expected. Setup was simple, and it worked smoothly for moving my files without any hassle. Overall, this is a great product if you need a reliable way to back up or transfer data from your phone. I would definitely recommend it.

Like it
Very nice and fast. Plenty of room for what I need it for, transfer between desktop and laptop. Simple to use both ends. Transferred 1.2 Gb in seconds, 40.5 Gb from another external slower hard drive in about 4 minutes. Fast enough for my use. Plus the case is a nice touch. Built solid.

My Favorite Flash Drive, Fast, Durable, and Extremely Versatile
This is honestly my favorite flash drive I have ever owned. The solid metal body feels exceptionally durable and premium, and the dual USB-A and USB-C connectors make it incredibly versatile. It works perfectly across all my laptops and devices without needing adapters, which is enormously convenient. Performance has been excellent. Transfer speeds are fast, the 128GB capacity is generous, and the drive feels far more substantial and reliable than typical plastic thumb drives. This is one of those products that quickly becomes part of your everyday carry because it is simply so useful. If you need a fast, high-capacity flash drive that works with both modern USB-C devices and older USB-A systems, this is an outstanding choice and offers excellent value for the money. Compatible with Windows, Linux and Mac

Great Flash Drive for Large Files
We purchased this for my husband and it has worked great for his job. As a technician, he now deals with extremely large software and diagnostic files, and this flash drive has handled them without any issues. The dual USB-C feature is very convenient and makes transferring files between devices quick and easy. It has been reliable, fast, and a great value for the money. Definitely a great purchase for anyone working with large files.

Good, fast storage, but it gets too hot
Solid feel, fast data transfer, upload and download. It gets too hot, causes concerns about possibility of data loss or corruption. Digital micro circuits are very vulnerable to heat

Awesome
I’m extremely happy with this computer drive! It was very easy to install, and my computer recognized it immediately with no issues. The speed is impressive—everything loads faster, and file transfers are quick and smooth. I’ve been using it daily, and it has been completely reliable with no lag or errors. The build quality feels solid, and it’s definitely a great value for the price. Whether you’re upgrading your system or just need extra storage, this drive does exactly what it promises. Highly recommend—would absolutely purchase again!

Speed was as advertised - rare - and durability outstanding
I just bought two USB gen 2 sticks from different vendors. This one claimed to be reading at speeds of 550 MB/sec, and I was leery. So many items never live up to their own hype. Well I have a slick tool now to measure such things, and this **delivered**. I am using EaseUS DiskMark which is part of their Partition Master Professional app. Sure enough it slightly *exceeded!!!* 550 MB on Sequential Read. For those newer to drive speeds in general, Sequential Read is the fastest (and so the metric companies claim), followed by slowing Random Read, Sequential write, and Random write (writing is just slower). Poor quality sticks often have a decent Read speed, that they use to market it, but terrible write speeds. This stick delivered! Its worst stat, random write, had only dropped to around 400 MB/sec which is an outstanding number and lack of the usual degradation in speed. Top marks. But the stick itself is a joy, almost space age. This stick has the feel you could whack it with a hammer all day. Ive had metal thumb drives before but the aluminum never felt sturdy. whatever alloy this is is tough as nails! In the photo, the little flip-back bar protecting the USB-C port looks pretty tiny - I assure you its no joke and *absolutely* will protect the port. Same goes for the other end and the USB-A connector cap - blast proof! The pouch for a keychain it comes with is also of high quality with a focus on durability, both in the leather-ish material, and especially the ring itself - its not going anywhere. I would have written this review just for my happiness with its speed, but the physical durability really puts it into a different category. At this price point there is just no reason to buy a cheap plastic thumb drive, and one where youre unsure of how badly it will degrade (if it even meets) its listed speed. This delivers on all fronts and is so robust it will last a lifetime. Slap it on that key chain, it can handle the abuse. drop it on the floor, stomp on it, no effect (im not joking). Absolute GEM of high quality mixed with durability and speed. This brand is now up there with Kingston and Samsung in my book (which is a long list of buying cheap disappointments)

Tasarımı çok iyi ve kaliteli bir ürün tavsiye ederim.
Ürün çok hoş ve kaliteli duruyor veri aktarırken aşırı ısınmalar oluyor eliniz yanacak derecede, hızı iyi dışı alüminyum sanırım bu sebeple ısıyı dağıttığı için bir süre sonra oda sıcaklığına geliyor hoş bir ağırlığa sahip hissiyatı çok güzel yanında koruma kılıfı var anahtarlığa takılabiliyor. Üründen memnunum ve tavsiye ederim her hangi bir sorun yaşamadım ısınma sorunu olması bana normal geliyor gövdesi alüminyum metal ısınmayı dağıtıp kolay soğuma olacaktır. Teslim tarihinden önce geldi bunuda not düşeyim.
