I have some short videos I want to join. I tried the trial version of Boilsoft video joiner and it worked well but read on the forum here that they give no support should one need it. I bought ImToo video joiner as on their website it said 30 day money back. Sure..the check is in the mail. To join the videos it took over 4 hours and this is for a video that is less than a hour long. After it was joined it was unwatchable, waves in the video. I removed it from my computer and ask for a refund, not a word from them. Lucky I have paid for it via paypal and have filed a claim with them. Buyer beware of this software.
