Not that bad, not that good either
For Flipper Zero - IR Blaster by Rabbit-Labs™
Parcel came beat up like trash but so far the item works. Specially chose Fedex as a carrier but regretted doing so just for purpose of speed wise. Tested, it works like it should but doesn't work across rooms that is covered by a wall so in theory and practical, you still need to point the IR to the device you trying to control. In terms of range, it was a good buy. Thank you Rabbit!
SideNote: It works with RougueMaster firmware now that it has 5v and sending signal to external device in IR menu

Sorry to hear your blaster packaging arrived damaged / beat up, Especially by FedEx as I've had really good luck with them over USPS lately. In terms of performance, you should see much improved range / reflection off surfaces, but the blaster despite being more powerful than the built-in emitter, cannot break the laws of physics :^)
Please send me a message and I can see about troubleshooting and/or replacing the blaster if needed.
Also, there was a known bug in RogueMaster Firmware that prevented the blaster from working properly. I have been told this bug has been fixed in the latest firmware build and advise running the latest build if possible.
