3 x GekkoScience COMPAC F with Fan Upgrade + Bitcoin Merch® 7-Port USB Hub - COMBO Up to 1.05+TH/s

The USB strip doesn’t stay balanced on the table and these fans are actually pretty noisy. These fans are connected to the Mars Lander. Looking back on this purchase I should have gone with the 3x compac a. However I have had problems with keeping the Mars lander hashing continuously. Spending a little $$ might have given me a bit more power but it would have also created a deeper regret when it’s not reliable. I thought about combining a larger 12x-15x usb strip with 3x compac f and 3x compac a and connect it to the mars lander but support couldn’t give me insight into this idea. When I asked what was the highest hash rate the mars lander could produce the support team member literally said “the maximum amount” without providing any more details.

Nice little set up
Only problem is I thought I would be earning a little something from mining but from what I’ve read up on you only earn if you hit a block and that’s like winning the lottery but it’s a bit of fun for me expensive fun
But would like to find something to mine in the future that will pay small amounts into my crypto wallet
Would like to get the 909 miner as well at some point to ad too but a bit pricey for me at the moment in the future

So, if you buy these miners expecting to profit, don't. These are incredibly fun to play around with and lottery mine with. The fans are noisy so I wouldn't put them somewhere where you need silence but i don't mind the noise at my desk, personally. They work as intended. I don't have them overclocked and they still average close to 300 gh/s a piece. Setup was easy. Had them up and running in about 6 minutes total. Check them out if you want to play around with some usb miners but, again, don't expect a profit from these :)

Product is ok, price is probably too much considering also I had to pay 155€ of customs fee for something that's not for "production"
Fan are also a bit noisy.

These compac F miners work. The issue is POWER. Even the provided 7-port hub stuggles to power the miners (in overclock state).
The Compac F requires a hub WAY OUT OF SPEC. Hence nearly impossible to find one.
My personal experience with the Compact F is a max clock range: 450-490 MHz. Not sure why I get varying results, but its a power thing.
The listed overclock of 400 will not get you to ~334 GH/s needed for a total (3 device) 1 TH/s.

If anyone is aware of a USB hub with over 3.1 amps per port - LET ME KNOW.
