ACASIS NVMe M.2 Duplicator, M.2 ssd cloner Dual-Bay Offline Clone, USB C to NVME Docking Station for M2 SSD M Key Hard Drives Enclosure

Yes, the status lights are difficult to see in normal lighting because they are so tiny. But this is not a significant problem; it is just something for the manufacturer to improve on the next design. I used this to upgrade an Asus VivoBook S15 (Intel Core i5) by copying the factory SSD to a Crucial P3 Plus 4TB PCIe Gen4, purchased on Amazon, and it booted just fine. (I have 2 of the Crucial SSD sticks so I did this test twice.)The copy completed within five minutes and I did not notice any significant heat during the copy.The same test did not work when I tried to upgrade my older Asus VivoBook 15 using the same Crucial SSD sticks. The copy succeeded fine but, when either of the sticks were installed, Windows 10 would not boot. The factory SSD from the older Asus has two notches rather than one, so the problem might be that the particular SSD that I purchased is incorrect for that laptop.

These types of devices almost always disappoint. They rarely work well. This one does its task. It clones a 512GB NVME in about 5 minutes. This is great for doing system testing and software installation test cycles, where you can't use a virtual machine. I have done over 10 clones without a single failure or error.It DOES get hot, but it is all aluminum and doesn't seem to be bothered. The LED lights give adequate status info for the purpose. You do need to use its included power adapter to do a clone; the thunderbolt connector didn't have enough power and it simply refused to initialize.

I have no idea how this got good reviews. I was able to clone 3 or 4 drives before it just stopped working. The cloning light would be blinking, but never complete the cycle. Also, this runs so hot that you can literally burn your fingers on it. I hate to leave bad reviews but I also hate getting ripped off. This sisn't worth buying. Waiting for a Startech cloner to show up. At least they have support.

Received the EC-6605. It was well packaged and came with simple instructions. The product looked very well made. I was interested in just basic offline cloning. Setup was easy, just slot the source and target NVME's, plug in the power, press the power button on, then press and hold the clone button for a few seconds until the lights started flashing. Cloning took maybe a few minutes. I was going from 256GB to 1TB in this instance. It did leave unallocated space, which I had to go into Windows and adjust, but overall it worked flawlessly.

It worked after the 4th try. I tried offline cloning exactly per instructions to no avail several times. The likely trick is to initialize or format your brand new m.2 NVMe before cloning. That and contrary to the precise interpretation of the instructions, DO NOT hold the Clone button down for 3+ seconds UNTIL all the progress lights start flashing. Just hold it down for 3'ish seconds AND RELEASE as soon as all 4 lights power up; they will start flashing in less than a second as intended. If you hold it until they start flashing and then release (as instructed), it for some reason appears not to work. So the cadence to I found successful to use is: 0) Initialize the target disk if possible 1) insert source disk 2) insert target disk 3) plug in power cable to cloner 4) push power button 5) wait for the 3 side blue leds to light up indicating drive recognition 6) Push and hold the Clone button for 3 seconds JUST until all 4 progress leds turn on, then let go. 7) Observe/confirm the progress leds are all flashing and wait for them ALL to stop flashing indicating process completion (clone time depends on drive size/speed). 8) Once all 4 lights are on/static, press the power button to turn off 9) unplug power cable 10) remove drives and install Target drive as planned. As directions state, you will likely need to "extend drive" in Computer Management to recoup any unallocated space from a larger target drive. A WORD OF CAUTION: This device begins to excessively heat up once plugged in; even with no drives or activity running. Do not leave it plugged in when not watching it. Do not leave your M.2 in for any longer than required. My Laser Infrared Thermometer recorded the device surface at 143+ degrees F during operation and again after a cool down and no drives installed. The top-end safe heat range for an M.2 drive is around 158F; too close to potential damage for my liking on a new 2TB 990 Pro. It may not be a fire hazard, but I'd treat it like one for due diligence since it heats up at all times. Or mine does.... However, once it works, it's great. Have done a couple drives now so happy with the purchase. Pricey for a cloner compared to cheap m.2 cases but way faster than via USB cable.
