This app works well and did exactly what I needed. I had an issue with the billing system-- the "7 day free trial" is not really true, because they don't downgrade you to a free account until after the first billing cycle meaning you have to pay for a month regardless... but after I expressed how I was unhappy with this and contacted the team they refunded my bill and cancelled my subscription promptly, so I appreciate that. I would recommend this app because it works perfectly and is easy to install but I don't get enough use out of it to justify paying for it.
Does work really well. Unfortunately it also seems to really slow the store down. Went from mid-30s to 40 site speed, now down to about 25.
