1 - Deep Blue is the best match for E3 colors.
2 - SF's sabers (except for like... the Prodigal Son, which doesn't use one...) come with the covertech wheel on the saber already installed (except again for the Bane, which sends it included so you can choose which side to install it on). The covertech belt clip is a seperate purchase, and costs $10.

I have unfortunately heard some things about packages not showing up/things not working correctly and there isn't much word from customer service about repairs or replacement parts.
I've never heard of anything like that. The couple of times I've had ANY issues with a SF order, customer service (which is lead by our very own DarthMario here on the forums) has been spectacular, on the spot helping and doing everything and more to make things right.
I also have some concerns about the electronics, as I've seen that the in-hilt rechargable battery doesn't last very long, and is a bit delicate. Is there any stock in these claims?
I have never in my life heard a 18650 battery described as delicate... the battery life is estimated around 4 hours runtime, though I've heard of several tales of people getting up to 6 or even 7 on champion sabers. I would personally say no, there is 0 stock to those claims.
Preferably within the last year or so, because some of the claims I've seen are from years ago.
^ This. More this, and EVEN MORE THIS.
SF is a company, and much like ANY company on the market, they have their flawless, spot on side, and they have the side where a few slips happen. This is life. This is EVERYWHERE. Of course, for every negative review you see, it's pretty safe to assume there's about 100-200 positive experiences that simply weren't reviewed. People just can't be bothered to rave about a good experience, because we've come to just expect that as natural. We are all, individually, supposed to be treated like Kings and Queens by every business we ever spend money with, and if we get any less, people flip out. The simple fact of the matter is also that some people can never be satisfied. I've worked in customer service for about fifteen years now. There are people out there that you can do stuff for, bend over backwards for, break policy for, go above and beyond in every way for....
And they still post negative reviews for you on social media or call corporate to complain. Where this is a smaller market, more centralized around a hobby, the reactions are even more polar. SF sends out 200+ sabers every week. It's safe to assume that out of those 200+, there's going to be a couple issues. Parts will break. Things will fall out during shipping, or a solder joint will weaken and break when the box is chucked at the back of a truck for the tenth time. Some of it's a weak piece of solder that they picked up at SF, some of it is the tech was in a hurry because he had ten sabers to do in the time it takes him to do three, because they're pushing that hard to keep up with demand, and some of it is shipping.
In the end, SF's customer service has come lightyears, and if you do happen to have one of the unfortunate incidents that exist in this world, rest assured that they WILL handle it, and to the best of their ability.
