This is a solid saber to get started in the hobby with. It's got a unique design with pleasing aesthetics and a sturdy, strong build quality. I've been swinging this around for a few days now, with the occasional bump, and even choreographed a duel and engaged in light sparring with another, and I've had absolutely no issues with diminished or damaged qualities.
As for the Xeno V3 RGB Premium core, the sounds are great, with good motion tracking and a quality speaker. The option to mute is nice and the customization with the sounds and colors are outstanding. My core advertised being able to hold 25 different sound fonts, but it came loaded with 34, and I was able to add a 35th on my own. The Xeno Configurator is necessary for an easier customization interface.
I got the 37 inch normal blade, and it's extremely well put together. As mentioned, I engaged in some dueling (none of it was with full power swings), and the blade held up like a champ. Being base-lit, it will dim a little towards the end of the blade, but it's not bad at all.
The hilt is phenomenally built, being entirely metal with a nice amount of weight to it. I had mine fitted with a covertech **** and the belt clip, which worked great and made me feel so cool walking around with it (yes, I fully acknowledge I am a giant nerd).
The price I paid was under $250, which is not terrible at all in comparison to some of the other vendors online, especially for the quality you get. I'm not an expert on saber quality vs price, but SaberForge has a good reputation online and I'd like to add my sentiments to that notion.
If you're looking to get into lightsabers, the SaberForge Acolyte Mk2 Eco is a great first option. I will be buying again from SaberForge.
