Jane's Review: Should I buy this product?

Jane's Review

It depends on what you are looking for. Let's go over the reasons why buying this construction protractor now is a good idea, and also things to consider before you decide on this item.

1. This construction protractor has positive 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 construction protractor has positivereviews on the internet, and based on current trends, it's likely that people will like this construction protractor 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

2. The price might go up, so buy now if you need this!

image/svg+xml Highest Price Lowest Price $51.77 $36.02

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 gone up, resulting in a 1.35% price increase.

Next, we need to look at its highest price and lowest price. Historically, the highest price point for this construction protractor was $51.77, and the lowest price point was $36.02. The current price isn't close to either the highest or the lowest price point, so it's a fairly reasonable time to make this 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, the price tends to stay more or less the same. Not a lot of price movement is expected, but the price could still move in either direction by a smidge.

Considering all this, will the price go up or down in a week? Based on past price points, I expect the price to be $46.88 a week from now. It might be best to purchase as soon as possible before the price becomes too high.

3. Baseline is one of the best selling construction protractor brand

Baseline is one of the best selling brands among other construction protractor 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. Manufacturer has generally positive reviews on their other products

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. The manufacturer of this product, Baseline, has generally positive reviews on the internet. It's generally a good sign if the manufacturer has good reviews overall. If your purchase decision heavily involves how well they make their products and treat their customers, and if you like this product, I'd go with this product!

5. There are other options, but don't look further if you're looking for a product with best reviews
