Let us know how they work out after you've used them awhile.
In my mind, these are primarily meant for use with powerdrive bits as opposed to insert bits.
The bit on the left is a power drive bit and you'll notice that above the black sleeve you do not see any silver. The one second from the left is a standard insert bit and you'll notice that the sleeve is not fully come back up. The bit is retained, it's meant for power drive bits.

The bits seat a full 3/4 of an inch, so a standard 1 Inch insert bit won't work without using a power drive adapter. The adapter works fine, but you need to use one especially for 1-in bits.
Pull the sleeve down, insert the bit and it locks in place. Pull the sleeve down to release the bit; easy enough. I have a Milwaukee driver where you just push the bit in and then you have to pull up to remove the bit. I found it easier to pull down than to pull up, but with the Milwaukee it is easier to put the bits in; obviously.
I like these well enough that I own a few sets of them. I find them particularly useful when I'm using powerdrive bits because power drive bits don't work real well in most of my screwdrivers with changeable bits... Or at least this works better.
I've always liked this type of handle, but if I were going to be doing a lot of really hard work I would prefer slightly softer handle I think, but these days if I'm going to do that I'm probably going to have a driver with a battery.
If I'm just going to use insert that's I'll probably just bring an adapter that has a power drive on one end.
I've had my sets for less than a year but I use them quite a bit.
As a disclaimer, I have numerous bit sets that I've created. One of my common go-to's is a set of PB Swiss power drive bits and when I grab that set, I almost certainly have one of these malcos with me. Otherwise, I probably bring along one of my snap-on drivers.
