I ordered an L3+ have been using it for a month. The difficulty is going up like crazy. By the time September batch starts shipping the machines wont be generating much. Besides that I have noticed this with Bitmain products for years now. And FYI Batch 1 of this miner was sold out in minutes. Another batch will be coming up soon. It says that one machine makes over $200 per day but by the time we get it it would make less than half of that.
