I ran the L21 for a week now, so far so good. Hash rate seems to be stable at 480-500 M/s (not 550 as advertised) i'm no sure if the pool affects the hash rate or not ( i'm using litecoin.org ).
It is running very loud which is not considering to let it sit in your house. The miner is running cool ( i guess the high speed fan make it running cool ).
Some people say it's way overpriced but L3+ is $2000 right now at bitmain.com, i'm not sure if this is still true Grin

. Shipment speed and customer service at Hyperbit are ways better than Bitmain too.

I'm trying to mine with other pools to see if the hash rate increase, if so may be i would get few more.

We ordered almost $40K in miners from Hyperbit. They were a month late, promised free shipping (which they never did) and promised to compensate us for the lost time (they never did). As a result, we ordered 20 L3+ units, paid with BCH, confirmed in a few minutes and shipped early. Over the last few months, Bitmain has significantly improved their customer service. I usually get responses to technical questions within 48 hours. Not so w/Hyperbit (at least for us in general). We show 585 MHs on miner interfaces, but pool data shows low to mid 500s. VERY loud. If you have them at home, go with the L3+
