here is a review I found seems like they work ok (at least from this)

http://bitcoinist.net/review-of-the-baikal-150-mhs-x11-dash-asic-miner/

thou there site says 88 dash for 1 unit of the 150mh version and with Dash at 8.44 per dash = 742.72 per unit as we speak

https://www.coingecko.com/en/price_charts/dash/usd

now as they mine you get this according to the below

usint the 150mh speed above at 40 watts and 14c kwh

you'd get supposedly below

Monthly    11.43659847    0.13196702    $96.83    $4.03    $0.00    $92.80 profit after electric

But the DASH as an example difficulty is doing this

look that over for the last month ..wow..this could go all Scrypt-N real soon....ugly ugly

So price is still to high for a unit with what is going on with difficulty imho we will see
