We've had good customer support and their custom pricing, although more expensive than other solutions, is worth it. The ease of use and integration in-app and with push notifications is excellent.
Easy to plug into your app, and I like that it’s supporting attach screenshots which are very important for CRM.
The service itself is of good level, especially the integration in the game is of good value. Also the different tag options make it easy to prioritize the answering of the issues.
Customer service was terrible. The bait & switch pricing.
On iOS, using Helpshift is pain (from developer perspective). Lot of issues, updates break stuff.
Microsoft PowerBI as their reporting system was very hard to work with.
