Free trial? No, no, no.... SCAM

This program is such a scam. They allow you to begin using it for free, but don't warn you that in an hour they will lock all your work behind a paywall, unable to access what you have done. You need to at least be able to download it before they put it behind paywall, but they GIVE YOU NO WARNING. They also have the nerve to make it a monthly membership, not a one-off fee. I WASTED AN HOUR OF MY LIFE ON THIS CIRCUIT THAT I WAS ABOUT TO FINISH, BUT IT STOPPED ME FROM ACESSING IT.

Sleazy website. Screenshot your circuit and run.

Very sleazy, scammy website.

Not upfront about their pricing. Pretending to be free and then shoving a paywall into your face. Your project will be locked and you cannot open it until a subscription is paid. Even if this is your FIRST circuit. They DO NOT notify you beforehand.

I'm switching over to the Circuit-Diagram website. It appears to be 100% free, just advertisement based. That is fine. At least I would NOT feel scammed and betrayed when using their services.

I'm certainly NOT using this website anymore, at all. Just in case there is a marketing team who came up with this: Your strategy is costing you customers for sure, according to the reviews here.

They try to pretend it's free (it's not)

They try to pretend it's free, but after a few minutes, they force you to create an account.

Sure, okay, just my personal information, email, all that jazz, but sure, fine, whatever.

Then, a few minutes later, they force you to purchase a paid account.

If they were upfront about the charges, that would be one thing, but there is no warning. You're right in the middle of a complex project for an intense homework assignment, and--boom. You're locked out. Pay the price or pay the time to re-do it in another program.

Definitely not worth it. Run. Find something else.

Software is good, but useless unless you pay

I'd say the software itself is good. But when you create a circuit, a gray popup appears asking you to pay.

When saving a circuit to share to others, you need to login. When you login, and try to save circuit, it again asks you to pay for membership.

So leaving 2 stars because it's only money motivated software. Not good for learners.

I'm not sure what happens if you pay, but I'm not going to pay a company that's driven by their monetary greed.

Made a complete circuit

Made a complete circuit, randomly became greyed out and cannot access it without paying at least $16 a month. You can't even see if it works for you before you lose an hour or two or work and they try and claw money out of you since you just lost X hours.

Although I probably would have subscribed, after this experience I will never be back.

Horrible sales tactics

Expensive but good

Yes, the marketing tactics are bad. They draw you in by making you think you'll be able to design circuits for free, then while you're happily designing circuits, you'll quickly find you have to register and then pay. They need to be less deceptive with their marketing.

BUT .... if you do pay, it's a really nice circuit designer. True that LT Spice is free, but at the moment, at least on the Mac, it's not nice to use. Circuit Lab is nice to use; fairly intuitive and the tutorials are good.

One of the most terrible and evil business practices I have ever seen. Period.

So, you come to the site, with no indicators that you would need an account or a (paid) subscription to design your circuit. You start designing just a tiny circuit with a few transistors, and after like ~10 mins a prompt shows up: You have to create an account to work further on your circuit. Fine, okay, I can live with that, not that big of a problem afterall. Account made, everything seems fine - proceed designing. Another 10 minutes after that, another prompt: You now HAVE TO get a paid subscription to view what you created or work on your circuit (You also can't open the autosave). All the prompts are filling basically the entire window, you CANNOT see and/or even make a screenshot of the circuit you just made. You HAVE TO pay in order to not lose you work you just made. You either have to pay or dump the work you just did.

This is under no circumstances right. This is terrible. Do not use this website. Seriously.

P.S.: The Simulation tool is also complicated and weird to use. For short, not really usable unless you're an expert in Circuit Simulation tools.
