their self branded dryglove system looks like the RoLock 90.
Their dryglove system does look suspicously like the Rolock 90, so I emailed MODS and they responded earlier this evening.
Here is the text of my message to them:
"Hi, I am interested in your dryglove ring system. Could you please answer the following questions:
1. Are these integratable with si-tech qcs oval cuff rings?
2. Is this design licensed from Rolock in Switzerland?
I have a set of Rolock 90 on my drysuit and am looking for a set to install ony wife's drysuit. She has the QCS oval cuff rings.
We would like to stay with the Rolock 90 design so if yours are the same just rebranded we will consider buying from you.
Please let us know."
Here is their response:
"Thank you for contacting MODS Drysuit.
Here is the answer for your questions.
1. We have not tried it but just looking at the spec it could fit. Here is our spec DRYSUIT OPTIONAL FEATURES
2. We don't have a license from Rolock.
Hope this helps."
Given their lack of definitive knowledge if the product is compatible with the QCS oval rings, coupled with the slight aesthetic differences between their product and Rolock 90, my guess is they copied the concept of how Rolock works in the design of their product.
Without hands-on experience with the MODS drygloves, to understand their product better, it is not possible to recommend them as an alternative to the Rolock 90, especially since the Rolocks are available for within $30 of the current price for the MODS.
