I am a Bitcrane official dealer and they continue to do quite well on NewEgg for the T110 and T110S despite there being much more efficient and profitable miners out there. I think they have practically given up on advertising here since the miners who are on here are mostly concerned on ROI and that's fair enough.
BitCrane knows it's miners are not profitable and for anyone to hope to make money on this I can say dream on. But the hardware itself is well made, it's very pretty and is very easy to setup. I have however not had experience with the T-720 which to me, although gorgeous, seems way too power hungry for me to keep it running for fun.
The T110/T110s is more for the hobbyist miner rather than for anything else who are hashing not for money.
In general I think at the current BitCoin price level, almost all miners are unprofitable unless you have a source of free electricity. If you want something that is well made and is directed at consumers and just want to get into SHA256 mining for the heck of it, I would still recommend this miner since it's so much better looking than any other miner out there and I have no problems having it in my home. You pay the price of course but I think it's very strange to call into question their integrity just because they're small. Even the often quoted Spondoolies they're not cheap and probably wouldn't break even either at single unit prices.
I have had sold several miners of theirs and own 3 T110/T110s on my own (just cause I think they're cool pieces of BitCoin tech) which continue to hash today.
This was the video I made of a T110 in action:

They do have plans to have more cost efficient miners but I doubt they will ever reach the levels of BitMain though I'm not sure that's what they hope to be.
