When I first learned of Helium 10 back in 2015, I started with the free access to keyword and listing tools and that UI/UX experience was great enough for me to subscribe. Now Helium 10 is a no-brainer, as Helium 10 as added many additional tools and maintaining a high-level of UI/UX. I have been able to drop subscriptions to other software. My main daily tools in the Helium 10 suite are Cerebro for keyword search, Keyword Tracker to identify the keyword with the highest potential, Follow-up for auto-emailer, Profits for financial analysis and now I can add ADS this week and I'm looking forward to Inventory Management later this month, these I will use daily.

I have no cons with this software. It's like comparing Amazon to all other platforms. Amazon is not perfect but there is no other even close. Same with Helium 10, I have subscribed to just about every popular Amazon tool suite out there, no others are even close to the value from Helium 10 for the money. Ok, when I first started using Follow-Up I thought something strange was going on but support set me straight that I hadn't specified the ASIN for the auto-email. When you adopt a new tool you still have to learn how to use it. Is that a con or just real life.

I've had a very good experience with Helium10 and I'd easily recommend the Platinum plan. The Diamond plan is a bit overpriced for what you get as you just get the ADS software, which is fairly good, but it's becoming less useful as Amazon is building out more and more functionality in their Advertising console. I find that I don't use the ADS tool much.

Helium10 offers the full range of tools that you'd need for market research and running a business on Amazon. Since it's pretty much all you need it's handy that you don't have to look elsewhere for one tool here, another tool there. Most of the tools are quite accurate – accurate enough to make important decisions regarding product selection – and provide a significant amount of data.

A couple of the tools, like the inventory analyzer, are inaccurate, though they're not the important ones. Their customer service can take a really long time to respond to some issues, particularly ones that involve billing (sometimes it can be weeks rather than days).

Bad. The few features I make use of work really well. It seems every time I try to adopt a new feature I am met with bugs, or some 'try and buy' scheme that's not specified so they can easily get their hooks in me and force me to upgrade to their next tier. I do not think Helium 10 is an ethical organization. I think they're a bunch of talented and corrupt developers looking to get as much money out of their consumer base and they are happy to confuse their customers in order to keep their hooks deep in the operations of their customers. If I could go back in time I would have taken the less impressive feature-set of Jungle Scout to avoid the dishonesty of this organization.

Certain features work well. They come out with new features frequently. Be careful to vet new features before using as this company has a tendency to release features that appear to be half-baked and not quite ready to go to market.

Portals: they allowed me to create a portal (landing page) due to a glitch. I should never have been able to at my price tier of Platinum. I created collateral and included an insert in my packaging leading customers to the portal. The portal has a 100 page view limit, essentially making it useless. They say I have to go to their next price tier of Diamond ($250/mo) to remove this limit. At no time when creating the portal was I made aware of the limit. I also purchased a domain through Helium 10. Any domain purchased with Helium 10 has a limitation that it can ONLY BE USED FOR PORTALS. This limitation is not specified when purchasing. Now I've been trying to get them to migrate the domain to AWS for several weeks now and their development team is continuing to work on it. I'm now sending out collateral containing a landing page that goes nowhere because I don't want to upgrade to diamond. My packaging contains a 'products@MYURL.com' that isn't hooked up to a web server because the domain contains a limitation of only being useful for landing pages created through Helium 10 (again, they do not specify this limitation when selling you the domain) and I'm completely screwed if my customers follow my insert or try to reach me by email. Their support team continues to assure me that this will be addressed. They've been doing it for about 3 weeks now.

Good tools, highly variable customer service. It has been real good on occasion and real bad on many occasions

Full suite of tools for the Amazon Seller. Covers all parts of the selling cycle: Research, Listing composition, Keywords analysis and customer outreach

Often feels like a series of point solutions mashed together rather than a seamless suite of tools sharing common interface and process management.

It's great and it is almost necessary to have to become a successful Amazon seller.

It provides so much insight on keyword and listing functionality for Amazon and/or Walmart sellers. The team also provides extensive how-to and insight videos on running these businesses.

I don't love the "Black Box" feature, which aids in finding new products to sell. I find it difficult to use and not that helpful.
