It fulfills everything from automation to manual performance
The most valuable features of the product are the performance parameters it gives us, as well as the seamless connectivity with our automation suites. I am also pleased with the continuous enhancements made to HeadSpin. There have been many features added since we started using the product, and all of them are useful.

Cloud-based testing has simplified remote mobile validation and provides flexible device coverage
I was not impressed with how detailed their analytics and logs are from LambdaTest. The solution we were testing is being used because many of us are working from home. It was easy to implement because with a real phone, we have to bring a real phone to each person. Since three years ago, many employees have been working from home, so we were trying to find a solution for this challenge. We had no need to exploit the information for the analytics generated in the background. The purpose was simply to make it easy for our employees to access a phone. The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers. The contrast on a real iPhone provides better contrast than with the cloud solution. The only aspect that was less favorable than on a real phone was the contrast of the color.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable features of the product are the performance parameters it gives us."
"It has an interesting feature called AV box testing. A lot of companies that are in the OTT segment don't really understand what their streaming is like. They can't test for streaming quality. There are restrictions where you cannot simulate live streaming. For example, on Netflix, you can't simulate how a movie is being streamed on a remote device. That's why HeadSpin has got this AV box testing feature. It is a patented feature. They send an AV box to your location, and you can test live streaming, which is something that no other company does."
"HeadSpin allowed us to manage remote work during Covid, enable continuous automation execution, and facilitate collaboration between various departments (product managers, developers, etc..)"
"The most valuable feature is that this is the first connected intelligence all-in-one platform."
"The most valuable feature of HeadSpin it's the integration with other solutions; it is great, and I can search for an element or do a quick debugging on the application right on HeadSpin, which is very useful."
"Large companies and enterprises are using this product."
"HeadSpin is highly advanced; it has got all the performance structures to provide visibility into how my app is performing in the real world and helps to identify the gaps."
"The technical support is really helpful because we can set up direct calls with them if we want to. We can use Zoom or Google Meet to interact with them directly, and if there is an issue in our system, they will help us by reproducing the issue in their machines and trying to figure out a solution. The support is really smooth, and we like that they're very supportive."
"Without a doubt, LambdaTest is one of the big reasons behind our faster deployment and better team collaboration."
"LambdaTest offers geolocation testing in automation, which is amazing!"
"LambdaTest made a great fit here when considering the latest browsers on the product."
"LambdaTest proved to be a savior for us here, as one platform does the job!"
"It’s good to see, now that we are using LambdaTest, we can run multiple tests on multiple VMs, saving us hours of testing time and the maintenance cost of local infrastructure."
"The slow nature of a cloud platform was compensated with parallel testing, and now we are able to finish our testing job faster than it was before COVID."
"Using LambdaTest, we could run all our functionality tests across various browsers, OS, and resolutions."
"Automation and mobile testing have improved our efficiency."
 

Cons

"Sometimes, devices go offline and some features are not functioning on some devices, specifically on iOS."
"There is a great scope to improve professional services; the time to deploy is quite long, and while they can set up automation through scripts at this stage, they are very expensive."
"HeadSpin could improve on the user interface because it is very poor. The checks that are done on the iOS devices are very difficult, but for Android, it runs great. For all iOS devices, the user interface and how it interacts with the device are very poor."
"If you want to do some testing or check the devices manually or check the application in a particular device manually, it is really laggy. That's a disappointment because sometimes we would like to do manual testing when our local devices are not available."
"HeadSpin could improve on the user interface because it is very poor."
"Support and pricing could be improved."
"HeadSpin needs to improve the hardware. With the mobile, the battery life reduces and must be continuously charged."
"They should automate their onboarding. A lot of things are still manual. They can create a video assistant or something like that to completely automate the entire process."
"You cannot perform native-app testing, as they offer simulation for web testing only."
"I didn't like the solution's technical support and how they communicated and tried to fix the issues of customers like me."
"I feel that the automated screenshot testing takes a little longer on MacOS sometimes."
"There is scope for improvement in service account usage, LDAP integration, and adapting new devices and features."
"Analytics could be better because as of now, it gives basic information on test status and build status."
"Sometimes, when multiple users use the tool simultaneously, it can slow down, affecting efficiency."
"If possible to simulate the finger pinch, it would make it more realistic."
"LambdaTest's technical support comes in different tiers - most issues get resolved, but there's room for improvement with critical issues."
 

Pricing and Cost Advice

"It's not cheap, but there are a few different packages and different prices for enterprises with different product versions."
"We have a yearly license for 16 devices."
"I believe the licensing cost is cheap because it's a total solution, hardware, license and software."
"It has a yearly license. There is no other option. It is expensive. There are a lot of other cheaper players in the market, but it is like a Mercedes. You pay an extra premium for it, but you get the benefits. I would love to see them come up with project-based costing. Companies that are low on funds or new-age can do with pricing that is easily digestible. They can give them a pricing model for three months. They can provide a startup package."
"LambdaTest is paid per execution."
"The tool is not cheap, but it is not expensive."
"It is 60% cheaper and there is no fuss in maintaining the lab, so we have more time to do the testing."
"The pricing could be made cheaper."
"LambdaTest is on the cloud, offers both free and paid plans which start at $19 USD per month."
"The pricing for LambdaTest is affordable, and one of the reasons we implemented it."
"This is an affordable product."
"It is affordable as compared to similar SaaS solutions."
