App has been pretty great so far. My store mainly uses canvas and wall art, and they have the best canvas and art product selection I have seen for Print-on-Demand apps. I had trouble connecting my domain at first, but their customer service got back to me quickly and helped fix the problem.

Creating products and adding them to our store was easy. However, when a customer makes a purchase, the process is not transparent to them. Gear Launch does not send the tracking information to the customer when the order is shipped. In addition, only part of the tracking number is listed in the app when an item is shipped. When you click on the tracking number link, it always takes you to DHL's tracking site, even if DHL was not used for shipping, which results in always receiving a message that it is not a valid tracking number. You have to then manually copy and paste the tracking number from the DHL site into a search engine to try to find how the package was shipped. On our first order, we used this method to figure out that USPS was used. However, our customer's package has now been showing as "Shipped" for over 3 days and USPS still lists the package as not yet received from Gear Launch. We have had to update the customer on status ourselves by checking the order status in the app and then sending an email at each step...'approved for production', 'printing', 'shipping out', 'shipped', and then hunting down the correct tracking and manually emailing the tracking number. And now, three days after 'shipped' status, we still can't tell if the package has actually shipped.
Absolutely stay away. You and your customers will be very frustrated with the lack of transparency, and you will lose your customers' trust.
UPDATE: After the tracking information continued to show that the package was not yet received by USPS after a week, we had to refund the customer. We had already removed the GL product from our site by this time, and thankfully didn't have any further negative experiences for our customer. We have now also permanently removed the app. Will no longer do business with this company.

Unfortunately while I thought their platform was easy to use, I will be unable to continue. Today I was informed that my campaign has been suspended due to copyright/trademark report. However, I have checked all my designs and am at a loss to see where the issue is. I have emailed requesting further information in particular that actual product. To date no response, so I will be terminating by business, as clearly I am unable to run a business if I am locked out with no actual idea why. The email appears incomplete, I have emailed requesting further information as I also want to get to the bottom of this.
