I’ve been using the the HUSBZB-1 for about a year and a half ever since I started using HA.
I’ve “almost” never had any troubles with it…
I’ve only got some Sengled light bulbs connected to it and they have worked really well so far.
However, right after I got the stick and bulbs all connected and working i bought some zibee “compatible” Bosch motion sensors that were really cheap. And then I found out a couple of things. 1. they weren’t compatible with the zha version that HA uses. 2. The place where I bought them from had horrible customer service. When I requested a RMA to return them the guy basically told me he would gladly accept a return but he would charge me the entire amount of the order as a “restocking fee”. 
They’ve been sitting on the bench ever since.
Then about a couple of months ago out of the blue for some unknown reason the HUSBZB-1 stick started acting screwy. it would intermittently loose comms with the NUC i’m running HA on and/or the zigbee lights. I fought it for a few weeks then decided to try out zigbee2mqtt (which is my next recommendation after the HUSBZB stick) which would have the added benefit of possibly getting those “useless” motion sensors working since you can add functionality to the software to potentially integrate new devices.
But then while I was waiting on the CC2531 stick and programmer to be sent over on a slow boat from china 
I thought about the fact that I still had my original RPi that had a perfectly working instance of HA on it that the stick ran on before I switched to the NUC. I plugged the stick in there and it’s been working perfectly ever since 
So now I use MQTT from my main HA on the NUC to control zigbee devices connected to the stick running in HA on the RPi.
The zigbee2mqtt set up has the advantage of being cheaper than the HUSBZB-1 stick (US$45 on Amazon with prime shipping) even with buying the required programmer (~US$25 at Aliexpress) but like I said it takes forever to get shipped and you might have to put in a little work if your devices aren’t already included in the supported devices. But there are a bunch of supported devices already so the chances of that are less than what you might think.
