BD1791 I originally wanted a tollyboy because his lock is supposed to be impossible to pick
I can confirm it, although @BikelockFugitive says different
BD1791 Neosteel offers an upgraded lock that's supposed to be very difficult to pick
I remember it was mentioned in The lock topic, and @HHelen even wanted to order one for her daughter
Yes, I wear 24/7.
For me is comfortable, even I feel I feel a little pressure on my buttocks just around the anus, but it's not uncomfortable, at least for me.
I don't even realize it anymore.
BD1791 How long did it take you to get use to it?
I spent several years using it only at night, but my cousin and my aunt started a few months ago and are used to it.
BD1791 I could get the cable and the opening and just see which one works for me. It's so hard to know without trying them.
We'll if you can afford it ... :-) Being able to compare the real things and decide for yourself seems great to me. (Though I can't offer personal experience with that modular Neosteel design mentioned, yet.)
(Semi-) Off-Topic:
While we're at it, order foldable D-Rings / connection adapters for accessories - ideally for at least 3 points (L/R side of the belt + crotch) - as well! Even if you are convinced they are extra, now.
Ines the Chastity Hawk and her relatives can surely tell you why it's always a good idea. 
Or you may read one post I made somewhere else ( https://unwedchastity.org/d/657-thighbands-with-padlock/155 ). If you don't want to fight through my notoriously long, pseudo-intellectual babble - although parts of me suggest you do, ofc 
- I can give the extreme conclusion: Ordering d-rings / connection points for accessories is a chastity-wise preparation just in case, and an economically sound decision.
Small addition on modular designs in general:
Modular designs could involve certain alterations, like extra joints and screws or bolts to link the parts, which could annoy, e.g. pinch at worst, or require extra cleaning.
Please note: This is just a theoretical, general consideration, not one from knowledge of the current Neosteel Solution. I don't want to spoil nor advertise. Owing to the shop maintenance downtime, I can't double-check as well, atm. If you think that concern holds for your desired design, I suggest talking about it with Neosteel as well.
That being said, again: If you can compare different configurations first-hand, that's great.

Does this make it harder to hide under clothes? Are D-rings more for bondage. Sorry if my lack of knowledge is showing. I'm not trying to offend. I just really don't know.
I'll read through the post you suggest when I have a free min.
Why are thigh bands something we might want? Again, sorry for my lack of knowledge.

This is a really good thing to consider. I'll reach out to neosteel and ask before I order.
I'm not sure on price because the store is still down. Talk about working on being patient
