I have used these gelatin capsules with good success - so don't let the "negative" reviews deter you (>80% satisfaction is pretty good, in my opinion!).
I purchase bulk powders from Bulk Supplements and other sellers, which often times can be put into a shake, but sometimes the product is just too gritty and dense to be used in a shake (i.e., garcinia cambogia). Other reasons I create my own capsules is because it can be cheaper and I don't worry about all of the weird additives, although I don't usually get too bent out of shape about additives, unless it is some sort of sugar. Also, if you have a small scale, sometimes you can be shorted on the milligrams by some companies...it happens, I guess...but that doesn't mean I like it!
I have not had any issues using these capsules. I actually like the feel of them right out of the bag - sounds weird, I know, but they are thick and easy to grasp. There are other capsules that are very thin and very slick, making them easy to bend and destroy before you even get the powder in! I have found that different powders work differently, and I found that the lighter the powder, the more capsules I lost once I compressed them using the Capsule Machine. Here are some examples:
Cissus Quadrangularis: powder is dense but very humid/sticky, sticks to everything in spite of having 3 dessicant packages in the jar. I have not had any issues capping this powder. However, the longer the CQ is exposed to air, the more humid the powder becomes, which would make capping impossible (so I cap a maximum of 72 capsules at once). Zero capsules lost.
Calcium Pyruvate: powder is granular and very dense, not humid; very dry and easy to cap. Zero capsules lost.
HMB: powder is very light and almost fluffy; can begin to stick to fingers after the first set of caps are complete. I lost 3 capsules during the joining of 72 capsules. I don't like that this happened, but it did. Do I think they were defective capsules? Probably not (but I have seen ONE). I think it just depends on the powder being capped, and how meticulous I might need to be when joining the capsules.
Overall, these are easy to use and are of good quality!
I hope this review helps someone. :
