Great performance i put this shaft through a series of test with different tee heights against my Denali Blue shaft as i have a half swing due to Partial rotator cuff surgery and low swing speed 85-90 and it out performed my old shaft with Awesome Carry results with great impact of the club face thanks for making a shaft for low swing speed guys like my self

As an 85 year old golf enthusiast I quite happy happy to gain some distance off the tee as hit it straighter.

Great driver. Improvement of aim tremendously.

Wow. Fast and easy. If you want to add distance and reduce dispersion this shat is a must have! As a 69 year old player hard to teach the old dogs new tricks. Who knew all it took was a Jupiter driver shaft!

Has helped improve my accuracy and distance. I would strongly recommend this shaft to anyone.

Longer and straighter. My steadfast delivers as promised. My miss is a bit over the top high fade. This shaft has allowed me to hit more fairways and helped lower my scores. Upgrading 3 wood next.

These are great shafts.....since putting them on I've improved my accuracy and gained a little more length. ....so far I've bought 4 shafts for the driver and im happy with all of them. I'm going to try out the three wood shaft next.

I have no idea how there product is. It was due to arrive 31 Aug. it is 8 Sep… the FedEx thing has no update, I ordered 11 Aug. I would have paid air shipment. I have sent emails, call there 800 number and I get no answer. So if the product is superior great…. But as for delivery and customer service. I likely will never buy again due to that one fact….

Placed my delivery order on August 23rd, did not ship until August 29th then received on September 5th and I only received one driver shaft out of the two and it was the incorrect grip size. Quality looks horrible, returning immediately and requesting refund, don't waste your time.

Ok, granted the delivery time sucked 15 days. But, I played today for the first time with the Jupiter 1 stiff shaft and I was amazed. I gained between 10 and 15 yards hit the driver 12 times hitting 9 fairways and shot 71. It does what they claim it will. Hopefully the shipping will get better.

My journey has been a nightmare, yes, you will get "shafted". I made my Jupiter shaft purchase on March 8, a Saturday. My purchase confirmation from SF Jupiter stated the shipping method: GROUND (Ships Next Business Day).So, I expected the driver shaft to be shipped on Monday, March 10th. The driver shaft wasn't shipped until 4 days after promised.

Unfortunately, this shaft isn't working for me. I purchased the senior flex based on my 77 mph driver swing speed. It's simply too whippy, the club head won't keep up with the swing. It's like swinging my orange whip swing trainer.

In the FAQ's - "We offer a 30-DAY FLEX SATISFACTION GUARANTEE: If you don't like the shaft flex you purchased, send it back and we will replace it." So I made a request to exchange to a regular flex. I used the Golf Shaft Selector Quiz to determine the proper flex based on my driver swing speed and driving distance, the result is senior flex by SF Jupiter standards.

I knew that return shipping would be on me but when I received an answer to my request to return the senior flex shaft for a regular flex, this is the reply "When you send the shaft back for exchange, as we do not offer refunds, please make sure to include a note stating the flex you will need.  Once we receive the shaft back, we will invoice you for the professional adaptor installation and the return postage to you."

I feel Steadfast Golf is responsible for exchanging the senior flex shaft I ordered and replace it with a regular flex shaft without any invoicing monkey business! I just can't throw more money into something that's not a sure thing.

Steadfast Golf has a 1.44 customer review rating with the BBB.

I just wish I had researched them better. But, I did get shafted!!!
