What are you going to use it for?
I think you're going to be disappointed
I bought a similar budget lighting set-up in the past.
Cost maybe $200, with back drop stands, and a black, white and true green, cotton drops.
The stands are incredibly light duty, and the light output is terribly weak, IMO.
I use the stands to this day, for my strobes, does okay, but it's so light duty, that it's prone to tipping.
Depending on what you're shooting, I would rather save up a couple more bucks, and buy:
Yonguo flash: $35-50
Medium duty stand off Cowboy Studio or something: $20-40
And maybe some budget wireless triggers off Cowboy Studio or
ebay or something: $30 ish. Possibly less with a different product.
And maybe a cheap umbrella or soft box: $10-100.
I know the price adds up but, IMO, this will be much more of an optimal set-up.
Edit:
Sorry I noticed you said you already ordered it.
I'd say just hold onto the stands, and don't expect too much out of the lights
Any the umbrellas can be held on to.
When I got this similar kit, the lights just didn't cut it for me.
Maybe can do okay with some light product shot use.
