That is a nice kit.. few things I learned after buying a top of the line kitchen sink kit....(which was full of options and swap outs... from Austin Home Brew Supply)
Happy I upgraded to a 30qt double wall pot.... Now wish I had gone larger.
All the brew kits seem to have a 5gal carboy for secondary,,, but many believe secondary not required in general,,, only for a few specific uses. .. in hind sight, wish i had traded that off for a second bucket, or upgraded to a 6.5 gal carboy.
The included wing caper works... but a bench caper is only a few more $$ and it works better.
The included hydrometer worked, but the scale was so compressed (due to it reading over a large value) it was hard to read... Wish I had opted for a two item Hydro package to read that same large value (I have since done so)
Your linked kit does not have a long handle stainless steel spoon,, consider one.
I don't see grain bags, strainers, large funnels in your linked kit...if doing just extract, no need, otherwise add um... if your going to do specialty grain steeping , or partial mash.
You can make beer with the kit..... but you can add so much more to brew better, faster, different... so don't get to caught up on the "completeness" of any kit..
If you can find anyone near you that is having a brew day.. go watch them, and take not of the equipment they use to make beer. Then do it again with someone else..... it will be different
