So easy to use.....I was in need of a Quitclaim Deed for mineral rights, and PDFfiller was the only site that offered the form that I needed. What a find!

What do you like best?
The ablitiy to be able to edit documents in PDF format is great. Saving time. When we are bidding on a job i can use the form provided to us from the client. Very easy to use and has worked well ever time I have neede it. Another great feature is that the PDF filler is auto saved in your online profile... so you can take the documents with you.
What do you dislike?
some times when you go to open the PDF from my email directly... it does not up load... so then I have to down load the pdf on to my computure, open PDF fill web app then upload file..... not sure why it does this but it has happened more often lately than it did before.
Recommendations to others considering the product:
It would be great if the filler could be able to authenticate docuements, a big one for us is Bonding, When we submit a bond they require an e-bonding ( look it up) the ebond authenicates the signatures from 3 different parties and leave a digital paper trail that can be confrimed by the client. We recently had to do this and the one website mobile bonds.com has an interface that is not user freindly for set up... and we had to spend countless time with the tech on the phone for the first few bonds. If the filler is able to do this that would be great.
What problems are you solving with the product? What benefits have you realized?
Allowing us to make our bid proposals look great, avoid hand writing in documents, setting us apart from the rest. we also can share the file with my staff making it even better

PDFfiller makes work easier. Easily fill out forms online that don't provide you that ability. The program is very easy to use. Glad I have it. None, really. If there's any errors, it's probably from me, the user.

Resolution is calculated using the separation of two peaks in terms of their average peak width at the base (tR2 > tR1). In the case of two adjacent peaks, it may be assumed that the peak width at the base wb1 wb2, and thus, the width of the second peak may be substituted for the average value.
Resolution is calculated using the separation of two peaks in terms of their average peak width at the base (tR2 > tR1). In the case of two adjacent peaks, it may be assumed that the peak width at the base wb1 wb2, and thus, the width of the second peak may be substituted for the average value.
Equation (1) indicates that the resolution is the difference between peak retention times divided by the average peak width. In a peak with Gaussian distribution, the peak width is W = 4 (where is the standard deviation) and the peak FHM is W0. 5h = 2.354.
In chromatography, resolution is a measure of the separation of two peaks of different retention time t in a chromatogram.
Resolution (r) = 1.22/(NA(obj) + NA(cold)) Where r is resolution (the smallest resolvable distance between two objects), NA is a general term for the microscope numerical aperture, is the imaging wavelength, NA(obj) equals the objective numerical aperture, and NA(cold) is the condenser numerical aperture.
Equation (1) indicates that the resolution is the difference between peak retention times divided by the average peak width. In a peak with Gaussian distribution, the peak width is W = 4 (where is the standard deviation) and the peak FHM is W0. 5h = 2.354.
The resolution of an elation is a quantitative measure of how well two elation peaks can be differentiated in a chromatographic separation. It is defined as the difference in retention times between the two peaks, divided by the combined widths of the elation peaks.
The width at half-height is determined by measuring the height of the peak crest above the baseline, dividing by two, and then measuring the span between the rising and falling sides of the peak where the signal crosses the half-height points.
