An excellent compilation of expert reviews for amazon products. Very seamless integration. An essential starting point for researching products.
I've been using this extension for a while now and have found myself really depending on it to weed through items and show me information and reviews on things I'm looking to buy. There's just so much stuff to go through on Amazon and other online shopping sites. Lustre is great for giving me a place to start, I'm looking forward to seeing what else it can do! It's a really slick, useful add-on that really makes the shopping experience more fun and productive.
Interesting extension. Sadly only supports amazon.com so I had to uninstall as I only use amazon.ca. Will install again if this is changed.
Saves me TONS of time doing product research.
Lustre is great for narrowing down stuff from amazon to the top 5 best choices for a category that you don't have any prior experience in, especially around a specific price range. Although I wish there was greater clarity around why some are rated higher than others.
This is an extension I have been wanting for a while, and i was amazed that it is out. I have been using it for 2 weeks now, and i can't thank the devs of the extension enough. by far the best extension i have used on chrome. I appreciate the hard work of the developers and I really want to thank them all. <3
It never worked for me as I never saw a single suggestion no matter how much I searched on Amazon.
Very good product comparison tool. Helped me find products I wouldn't have otherwise found without deeper online research. Has a great user interface, non-invasive, nice aesthetic, and seamlessly integrated with Amazon. One thing to watch out for is better prices available than the recommended amazon link from Lustre as it doesn't seem to register all vendors selling the same product. I would like to see more personalized results on the Lustre rankings page to help narrow product searches. Overall great extension, definitely recommend it.
this is pretty cool, but it doesn't have newegg support, nor does it really support any pc components. the vr headset support is nice, but it rates the valve index lower than the oculus quest, which is a bit of a funny conclusion. anyways, i love this for general products, but it'll only gain a cult following if it has support for pc parts. thanks, devs! :)
This extension replicates what I was already doing to buy stuff (looking in Reddit, Wirecutter, CR, etc) + comparing prices. Definitely an awesome addition to automate the process of researching products. Only one minor annoyance: I wish it was faster. It takes several seconds to load the review cards after clicking.
