It is one thing to believe what the marketing team is saying through their sales pitch and what is realistic. The same goes for the netting because you are not going to believe what they are feeding you. They are just hoping to sell and that is all they care about. You have to believe what they are telling you is exaggerated.
I have to think the lifespan is always going to be under what you are hoping it is. I have seen this all the time, and I believe they start to overdo it with the driving range netting that is being sold. I would believe you have to slash what they are saying in half at least.
They are going to tell you it could go for 10-15 years, and that is a lie. Try to go to http://acedrivingrangenetting.com/driving-range-netting/ and learn on how driving range works.
It is going to go for around 4-6 years, and that is depending on how the netting is doing and how you are using it. There are some that might go over, but most will remain under the number that has been written here.
You have to deal with this and understand that is a reality you have to notice. You can't just go on it all alone.
