This company is the worst company to ever choose. 1. They make sure you sign a 58 page contract basically saying you allow them to take your money no matter what they do even with no results and fully covers them. I would never risk doing that again and would have them sign my own contract. 2. They US 3d printing which when I was with them I supplied them all the step CAD files from my previous completed prototype and they kept having computer problems for over a month which I was charged for. 3. They truly have a very non standard billing method you have to prepay $2200 a month regardless of what they do or don't do and at the end of the month I guarantee you u get an email saying all your time has been used with out any solid proof of work. (They charged me for two months which they said would be the maximum time for making small detail modifications to my prototype. End of two months and $4000 they hadn't sent me anything no pictures no proof of anything and no new prototype) 4. They have terrible staff poorly educated and don't no how to communicate. 5. If you like giving away money please send it to me instead. 6. Basically you are bound to what ever the staff desire to pursue not what you want because they have limits with the 3d printer they use which will truly limit the cope of what they actually can do for you for a reasonable price. For example at another company I had the entire prototype original and with modifications a second time completed for only $2500. FINALLY BEWARE YOUR CREDIT CARD COMPANY MAY DENY YOUR REFUSAL FOR NO DELIVERED GOODS. UNLESS YOU HAVE AMEX OR ANOTHER 100 PERCENT GUARTEED SATISFACTION CREDIT CARD BACKING COMPANY.

If you are first time inventor and want a working prototype. I do not recommend this company at all. Reasons are listed in bullet points. 1. PRG prototypes are made from a 3-D printer which is not good for durable use such a travel , mailing , touching , or presenting. Find a company that uses a CNC Machine , which use molding material and it's more durable. My experience with this company. The prototype was broken by the time I got it and it also does not work with the main objective I had it made for. The color , sizing , and material are all just bad. 2. The communication is terrible. Their main line is email, I expressed that I wanted to be involved more and it did not go any better. There were literally weeks where I did not get a response from them. I would send multiple emails within the same week.. no response until I threaten to not pay them and 20 minutes later I get a response. I was told I would a get a review/ time log on how everything was going. I received it once after writing an intense email of the customer service I was receiving. Again, if your looking to put blind trust in a company this is not the company. 3. My prototype is not want I want at all. The prototype is not feasible or working. Literally, just pieces sitting in a Kroger bag; I am starting over from scratch all over again and working the sketches I came up with and looking for another company. To answer your question I spent over $5,000 with this company and have nothing to show for it but
