May have gotten the wrong parts
I think I may have gotten the wrong phone case or beltclip because it does not stay in the belt clip very well

Okay holster
It works but it’s not very tight. It’s no where near as good as previous holsters have been.

Case great, holster ok
The case is awesome. The holster needs a bit more engineering on the holding clip. My phone just keeps falling off of the holster.

Iphone 17 pro max defender xt
Purchased new otter box defender xt camo case and holster for new phone. Case seems be sturdy but the finish is coming off very easily and the holster doesn’t seem to hold onto phone very well at all and always falling off..

Best 17 Pro Max case for active individuals
Solid case as expected from otterbox, far superior to other name brand cases I’ve tried for this phone so far. Holds up to the rigors of construction sites and everywhere else I go.

Weak retention
Have to be careful with it. The retention isn’t very strong and the phone will fall out of it pretty easily

Otter Box is nearly unbreakable.
Otter Box is a brand that I will always rely on. I will always stick with the defender series no
Matter what. The only drawback is that when you buy the defender, it doesn’t come with a clip. You have to receive the product, then use the code to get the clip mailed to you. I can see that years down the road, it will be an issue where you have to separately buy the clip
