I'll weigh in.....
While I did purchase a saber from them, it arrived as advertised and without issues. I didn't have to deal with customer service.
I like my saber and it still works as new--but mine has no sound, as I added my own.
Now--I do not stand behind recasters, thieves or anyone else that scams or treats customers bad--especially fellow RPFers.
I usually buy my saber supplies from the Custom Saber Shop, so my US experience was a one-off for an Obi TPM.
You got very lucky Hermes. I have had multiple of them on my desk for repair and had to literally replace the entire guts of more than 30 of them. As well, there are certain models with severe structural flaws. The lens assembly they used to use, and still do for their cheapest units, I had approximately 22-23 of them where the hot glue melted that held the hex nut onto the LED (a very improper electronic assembly), and the LED blew itself out. I've seen crossed, unheatshrinked wiring, unprotected lithium ions that were overcharged to over 4.5V (I actually watched one explode in front of me shortly after I removed it during repair). A raven blade holder that flew out of the saber with the blade like a zelda sword.. A "MHS Compatible" consular that wasn't compatible with EITHER of the MHS heatsinks.
The heatsinks dislodging from the LEDs were only the beginning of that problem. So many saber owners love swinging the sabers around without the blade in them, and I've seen it to the point where this hotglue has gotten around the outer parts of the blade, gluing the blade in. If this issue occurs while someone is swinging the saber around wtihout a blade, or with a very loose blade, that hot glue can easily spray on someone and cause third degree burns. (LEDs can easily reach 300 degrees C especially improperly heatsinked).
The Raven that I repaired was by far the worst off. They bought the saber at Dragon Con in Atlanta, GA. It was sold to them at around 80% off the price of buying the equivalent unit. The Blade Holder was improperly held into the saber (one set screw is not enough to hold something that takes that much impact into a device.) The LED was being powered by a flashlight driver meant to take no more than 3.7V (and it was being driven by 7.4). The LI-Ion batts that came with the saber (and they didn't give them a charger, and they were lead to believe it used AAs) were overcharged to approx 4.56+ Volts. I was advised by experts on LI-Ion that had they flown back to NYC, those batteries would have exploded. I may not be able to prove it, but, I do think it was a malicious attempt to hurt someone. Luckily they didn't trust the 80% off, or ultrasabers due to my warning, and called me up shortly after the convention to examine the unit. I removed the batteries and watched one of them explode shortly after (thank god it wasn't near me, I had smartly put it somewhere any damage could be contained.) Still, on purpose or negligence? Still would have been a severe injury caused by that.
