Have you gotten the RepOne yet? I'm on the fence between it and a Speed4Lifts.
I have not. Their last email update was Dec. 31 and didn't have any updated shipping info so we'll see if they can stick to their "late January" prediction.
I'm somewhat annoyed with the whole thing... when I preordered I was under the impression that they had the whole thing designed and ready to start production, but then every post on their social media has been about how they're testing this and that material and making design changes, etc. like they just started from scratch after the preorders. Maybe I'm just naive about how this type of product development works but bottom line is that it's going to get here at least two months later than they predicted back in August.
In the meantime I picked up a Speed4Lifts during their Black Friday sale. It seems to do the job although the documentation isn't great and some things have been confusing. They're apparently a Spanish company and some of the stuff in their online support documents were clearly written by a non-native English speaker... it's not a big deal but then if you go on their youtube everything is in Spanish. They only have three videos, one of them is more of a promotional thing and of the two instructional ones, only one of them has subtitles.
Straight out of the box it will give you an E1RM based on a default equation, but I found the number to be way off for me. I was pretty confused about the process of setting up my own velocity profiles and the documentation seemed to have a lot of gaps with regards to how to do that. I've been using it for about a month now but just got around to doing profiles yesterday for squat and bench. Eventually I think I figured it out and it should be good now, and give me some more reliable predictions of E1RM that I can use to track progress.
As far as actually recording the velocity of each rep it has worked great with no hiccups.
Once the Rep One actually gets here I will have to compare them and see which one I want to keep. Judging by what I've seen of it so far it seems like it might be more durable and it's supposedly more accurate because the cord doesn't have to be perfectly vertical. On the other hand, I asked them about whether it can do an alert when you hit a certain % of velocity lost from the fastest rep and they said that feature (which the S4L can already do) wouldn't be available at launch but they are "hoping to add it".
I think for you the biggest factor to consider is that if you order a S4L you'll have it in a week or so, and if you order a Rep One it will still be months away even if it starts shipping tomorrow, because you'll be at the bottom of the queue with all the other preorders ahead of you.
