It’s unreliable in a retail environment, which is where I’ve seen it used first hand. The customer pays from Aqua. It shows on their end that the transaction was completed and their balance is reduced. The merchant doesn’t receive the payment and the invoice eventually expires. Meanwhile the customer and the merchant are left staring at each other awkwardly while they try to figure out why “bitcoin is broken.” The funds from the failed transaction apparently return back to the sender, but it can take up to 24 hours. 

 I haven't tried it in a retail setting. I wonder if it is a timeout issue between the retail receiver and the additional transaction time going from liquid to swap to lightning. It is not fast.  

 not what i hear with retail here but will do a deeper dive Daniel 

 My sample size is 4 transactions with a 50% failure rate in two different locations.

I haven’t extensively tested it, but it has not earned my trust. 

 t-y 4 info, i will report back with a larger samplesize
