Jane's Review: Should I buy this product?

Jane's Review

Yes! I recommend this household ventilation fan based on price trends. Let's go over the reasons why buying this household ventilation fan now is a good idea, and also things to consider before you decide on this item.

1. The current price is in its lowest range, best time to buy!

Price is one of the most important factors in making a purchase decision. I analyzed the price of this product in four parts: its recent price change, when it was most expensive/cheapest, its price volatility, and a price prediction I made, just in case you want to wait.

First off, let's talk about its recent price change. The price of this product has not changed from March 7, 2020 to May 20, 2020, which means that it has steady and healthy supply!

Next, we need to look at its highest price and lowest price. Historically, the highest price point for this household ventilation fan was $126.04, and the lowest price point was $63.34. The current price is lower than it has ever been. This is definitely the best time to purchase!

What about its availability and price volatility? This is another aspect we have to dig into before buying something. I haven't seen this product being unavailable since I started reviewing this product. So as far as the availability goes, this product is solid. If you plan to make a repeat purchase of this kind of item, this is your product! In addition, I've seen a small amount of price movement with this product. From what I've seen, the price is likely to move up or down by an average of 2.56% at a time.

Considering all this, will the price go up or down in a week? Based on past price points, I expect the price to be $120.48 a week from now. It might be best to purchase as soon as possible before the price becomes too high.

2. This household ventilation fan has okay reviews on the internet

Some people have a great experience with a product, while some are unlucky and get a defected item and have to go through the whole process of returning them. Since people have different experiences about a product due to various reasons, don't read too much into one good or bad review. Reading multiple reviews with different ratings can help you picture how good/bad the product generally is.

This household ventilation fan has moderatereviews on the internet, and based on current trends, it's likely that people will like this household ventilation fan more a week later. I summarized what fans and haters say about this product above in the good/ok/bad table, so don't forget to read those since they paint the whole picture! And of course, if you want to read more detailed reviews, many of them are on Amazon!See More Reviews on AmazonSee More Reviews on Amazon

3. Professional Grade Products is one of the best selling household ventilation fan brand

Professional Grade Products is one of the best selling brands among other household ventilation fan brands. But I couldn't find any YouTube videos, Reddit posts, or news articles that directly mention this product, but this can be just me not looking hard enough. Will update this when I have more info!

One thing to be careful about here is that I'm not verifying if this product's maker is a household name or not. This section is more focused on whether this is proven enough by its consumers, whether people actually love this product.

4. The manufacturer of this household ventilation fan is unknown

The maker of a product is another factor you want to definitely consider before you buy anything. What if there is a piece missing or there is some defect in the product? With anything you buy online, there is a small chance of this happening. But don't worry too much, because Amazon has an amazing 30-day refund policy (Amazon❤️). Still, you want to make sure that the manufacturer or the seller has been helpful in resolving this kind of problem and/or has been helpful to its customers about general product inquiries. As for its manufacturer, I couldn't pull the manufacturer info of this product. It's likely that this product is produced by a relatively smaller manufacturer, or the seller of this product didn't put the manufacturer info correctly. I'd double check if the legitimacy of a manufacturer is your thing in making a purchase decision!

5. There are other options you might want to check out

'If you're looking for a cheaper alternative, you might want to look at a similar product from VENTECH. If you're looking for a household ventilation fan with best reviews, a product from Hydrofarm gets the best score on the internet. If your primary concern is whether the product is popular and well known, a similar product from AC Infinity I linked below is a better option. I linked all the similar products in the similar products section so please check them out! Or you can check other similar products on Amazon, too.
