Anyone get the $50 offer from Tmobile for using the Placement Assistant app from Saffron LLC?

EDIT: It was suggested to me that tmobile is a better sub for this post. I received an email from tmobile. Bulk of the wording below. At first I thought it was maybe scam / fishing attempt, but the link went to Tmobile's official site. This was my experience with it for anyone else who gets the offer and is wondering. I also wouldn't mind other folks' takes on it who know / use better apps. PS - none of the flairs seemed quite right. Sorry if I chose wrong one. Try our new gateway placement tool to earn $50 We’re inviting a limited number of members to try out a new gateway placement tool that can help you get the best possible experience from your T‑Mobile Home Internet.Try it out and share your experience, and we’ll give you a $50 virtual prepaid Mastercard ® ! After reading the details a few times I decided to give it a try. It's an invite only thing as they are rolling it out to different customers (according to Tmobile web site. Went to Google Play and installed the Placement Assistant app. Had to give app my router admin password, which felt kind of weird, but maybe it's normal for you folks using apps that let you control frequency bands and such. You also give it your house address. It brought up a satellite image of my house with a square grid over it and asked me to select where my modem is now. It then did some sensing or whatever and came up with a few suggestions of locations it thought would be better. A couple were not practical but one was back in my master bedroom, so I thought what the heck and tried it. It then brought up a circle with partial green bar and had me rotate my phone until it pointed at the green area. That was the direction they recommended I point the modem. This surprised me a bit. Previously I had the modem facing South, slightly to the SE based on what I could find of online tower maps. The new location is facing NW. The app said I gained 10 in signal. (db?) It then prompted me to enter the code I was given to receive my $50 electronic mastercard. The only problem I encountered was while I was getting the code from my computer, my phone locked, and then I could not get back to the place in the app to enter the code. It acted like I was starting from scratch, and when it got to entering my address, now it tells me this address is not available for the program. I'm guessing that is to try to prevent double dipping on the $50. The problem is apparently resolved though. We'll see. I entered a ticket via the app. Got a bot response with a ticket number. Then a couple hours later got an email from apparently a real person on the support team telling me they submitted it for me and I'll get my $50 in a few weeks. And to hang onto the email with the redemption code just in case. My take on the app: From threads I have read here, some of you are much more knowledgeable than me and this app might be too simplistic for you. But since I'm not very knowledgeable about it, I found the app helpful and easy to use. It APPEARS that I am actually getting a bit stronger signal based on speed tests before and after. It is difficult to say for sure because I'm kind of on the fringe / weak signal area and could not get it at all until about a year ago. So my typical speeds are in the 20 - 50 mb down (sometimes higher) which I know will make some of you laugh. But when your signal is lame, a bit of a bump is more noticeable. It's a bit weaker in the summer time as I'm in the woods - lots of water in the trees. And it often slows down some late afternoon / evening - which I assume is bigger load on the towers and packet priority. So I'm hoping this change helps the occasional buffering I see on my video streams during those times.
