Good so far; expensive, however, AND when I agreed to your discounted one year offer when I intended to cancel after one month, I didn't realize the sum offered was in addition to the $20 one month fee, so it didn't turn out to be such a great deal after all. I was canceling, because I honestly don't see myself using this much more if even ever again. However, for the discounted rate (WITHOUT the $20 added in), I thought 'why not?' I am going to evaluate over the next couple weeks to see if I really DO want to continue a subscription, discount or otherwise.

I subscribed to the PDF filler app on… I subscribed to the PDF filler app on Google. And without asking me they charged me. Then I contacted them and they didn't want refund my money until I told them that I was going to let everybody know about their app.

What do you like best? It's super fast to upload a document and simple to navigate the website. Filling out your PDF couldn't be easier! What do you dislike? The point where you save your document could be a little easier to understand but because I've been using them for 7+ years, I've got a handle on it. For someone just starting may find it a tiny bit confusing. Recommendations to others considering the product: This is a great platform to turn your PDF forms to fillable forms! It's easy to use and the price is nominal! Totally worth it! What problems are you solving with the product? What benefits have you realized? It's so easy to use! Make any PDF fillable! I have a tiny bit of OCD and filling in a form by hand just doesn't look professional enough for me so converting those forms to fillable using PDFFiller is a must!

Just what I have been looking for Just what I have been looking for. Very easy to operate once you get the swing of it. Typing over erasures may be a bit tricky, but you have to insert text in a blank space and then you will be abe to move your text over the erasure without any difficulty.
