Yes, I have used the Home Improvement / DIY one extensively.
My review: not great, but okay. Suffers from the same issue all of these no purchase fee ones do, lack of ability to spend the entire balance leads to spillage, but with Bunnings I tend to get pretty close, my average is around 50c left on a card as I always search what I'm going to go get first and check if it will zero out (or close to it) any of my card balances.
The operation of the card in store really sucks - it is a visa card but with no PIN so you have to sign the back of the card and sign every time you use it. I've had people at Bunnings look at me wide eyed when I ask for a pen to sign... Imagine if I tried splitting a payment
Where these are great are online orders. You can use them seamlessly online for click and collect. I recommend this where possible. I've used them online and in store at Bunnings and Bowens without issue around acceptance, never had a decline to date.
