So far, your Fb add seems to be going in the right direction. If its the first ad for the product, let it sit like that and get the stats from it. However, if its a recurring ad, you can increase the budget here.
P.S. For your abandoned cart, create an email campaign and try to pitch the consumers that left midway. Sometimes, they encounter a problem with payment gateway or get lazy to proceed. Give them a nudge with a reminder email and increase your sales.
You should try to tweak with the target audience in that case. If it is too large, try to reduce the number of audience and make sure to start your ad at an optimised time according to the target audience time zone.
