Selro is a very easy to use mulitchannel listing platform. The fact that you can manage all marketplaces in one go saves alot of time. Also i find it straight forward to download all my sold items, rather than going to each different market place to do this.
I have found the customer service very friendly and approachable. If you are unsure about anything, then they will take time out to show you and go through things with you that you are unsure of.
Selro is a great place to expand your eCommerce business
