BTC Lightning

So, I saw someone's post earlier about the lightning network and it reignited some dormant interest that I had about in the network and how it works. I started researching how to swap BTC for BTCL and I was able to find two services that can facilitate but, how reputable are they? I can understand that their services come at a cost and I am ok with that. However, I am somewhat leery of these services. How can I trust that they will do the swap as stated without keeping all or too much of the btc that I hand over? If anyone has any suggestions on a reputable, easy to use swap service, I would appreciate it.
