Question: are the irons graphite
Document: Very impressed with the quality of these clubs right out of the box and everything included. Wasn't expecting much for the price but once again amazon thoroughly impressed me!
Most people don't like the fact that these clubs don't say the Callaway name anywhere on them, but that didn't matter to me. I know they are a brand of callaway and the quality is there for the price. Great purchase! !
If it wasnt for the driver breaking I would give the clubs 4 stars.
I tried to buy a right handed set but the description doesn't actually say that until it was already ordered and shipped to me. This was not the hand that I want!!! Why is that the default and the description doesn't say it?I ordered this because I was hopeful about the quality.
I purchased this 18 pieces Golf set, but only received 17pieces. Hybrid 4 wasn't on the bag.Not find a place to place a claim for this missing item....Any help will be appreciates
I just started really playing the game of golf 6-8 months ago. I have mainly been using other people's clubs and the clubs they provide at the driving range. I finally got these clubs today (they are so popular they have been back ordered a month) and as I started swinging, I thought I had to write a great review. Great starter set from what I am getting from all my friends that have been playing for some time.
I guess they forgot to design them to be rugged enough to stand up to a beginner learning the game of golf. Since they are warrantied for 2 years, I guess I will continue to get replacement clubs as needed. Follow up:  I received the replacement clubs in 5 business days. They were shipped from Texas. I would rate Callaway's customer service as excellent. So far, I have not had any problems with the new clubs, nor the drivers I've used.
I got the clubs at the start of spring for an extra set. They seemed like a good bargain and after playing two rounds with them they work pretty good. They have a good weight and are balanced well. Only problem I had was after only hitting maybe 20 balls the head of the driver came off. I could see it happening if I had hit the ground with it a lot but this was not the case.
As a beginner, I received these clubs as a present. During my first lesson, I used the 7 Iron and by the end of the lesson the club was bent at the club head hosel. I called Callaway, and they are sending a replacement under warranty. At my second lesson, I used the 8 Iron. Three quarters of the way through the lesson I noticed that this club was bent at the hosel as well. Again, Callaway is sending me a replacement club.
