Amazing! I love these sabers so much. After researching everything out there I finally decided on the duelist bundle from SabersPro, and I'm so glad I did. They are awesome! The songs are really cool and react very well to movement and hitting your friend's sabers. They are super durable. I've had them for several months now and me and my friends go HARD in duels. We hit so hard their saber (not from saberspro) blade wobbles while mine says great. We've thrown them as hard as we could (very very hard, try holding in a backhand grip and using your whole body to throw it in a horizontal spin, its very powerful) onto rocks, grass, dirt, asphalt, and more. They have plenty of dings but the function is undiminished. There are a few small issues: the soundfonts are really col but it is hard to tell who is who (I found something on Reddit that helped) and they have some odd choices like having darkside Rey and Reva while not having Ahsoka or Yoda. The blade does randomly turn off sometimes, and sometimes it turns all the way off for no apparent reason, but it is easy to turn back on and keep going. The music feature never worked, but I just play it from a speaker. However, the blade modes, variable volume, two ways to change the color, and different sound fonts are all really cool. I love the motion ignition. Some pro tips: the handles are slippery. You do want grip tape. The sabers come with some, and it works well but wears out fast. I recommend lizardskin top of the stick tape like you'd use for hockey. Also, the price seems like a lot, but SabersPro has a LOT of sales that really help bring it down, and with two amazing sabers I think you get a lot of bang for your buck. Sorry for the essay of a review, but I hope you found it helpful. I love these sabers and hopefully you will to. May the Force be with you!
edit: I added a picture of me dueling with my freind. The blue and purple sabers are mine from the duelist bundle. The red double bladed saber is (I think) the padawan bundle from SaberCouncil.
