1. Is the product useful?
Yes... for storing old stuff that i don't want to dispose of.
2. Are you going to buy?
Maybe. Why maybe - since I'd still be needing a storage container after i seal this and the reason i'd be buying this is to have more space so it means i don't have any more left. I wouldn't also want this to be stuck in my cabinets without a structured container or some sort to maximize space.
3. If yes, How many pieces are you going to buy?
3 or 4 of the XL bags
4. Is the price affordable?
Not so... considering that i would need a vacuum cleaner. For me this is your weak point since not every household possesses a vacuum cleaner.
5. Do you want to give it as gift, resell, or for personal use only?
Personal use only.
6. Have you seen this item here in the Philippines?
I saw one sold in metro ayala grocery, i think the brand is Mr. Clean near the diaper section. What stopped me from buying is the gadget that vacuums the air since the initial kit is quiet expensive.
In a nut shell this is a hit item internationally but try to check on regular households, the masses if how many percent of them owns a vacuum cleaner. Based on that you can see if this is a hit or a miss.
