Great product!
I've been using two of these with my band to have the signal split to our Behringer X32 for in ear monitoring and provide the signal for FOH. So far, after more than 2 years of usage, there were absolutely no issues.
The quality of build is great - it's sturdy and XLR sockets show no issues after being used every week.
Sound quality is excellent taking into consideration the price of the units - signal is split in a passive way so it's weaker, however I don't see any excessive noise floor issues, also I've never heard any complaints from the FOH engineers on a gigs up to 200 people.
Strongly recommend this product, especially for the personal in-ear monitoring usage!
