A massive basket of great advice!Each pumps have their positives and negatives. Better than other? No. It should be said as "more preferred than the other". Otherwise, the market wouldn't be flooded with the pump.
Bathmate has portability, usability, and compatibility. It is designed for both air and water with advanced and simplified pump system. The negative side is the lack of pressure gauge and for good reasons as the gauge cannot be added on due to the relief valve design. Modding at your own risk of warranty.
The MityVac is designed same purpse as the Bath Mate, however the support is the entire brotherhood. The negative side is the lack of reservoir for the water trap. The most upbeat side is the cylinder for the higher pressure design using a thick wall for safety, accommodates all size penises, as well as the portability and compaction of the design most don't considered. On cylinder size does not fit all. Most designing manufacturers do not guarantee the parts, as well as the instructions on how to use it. Compared to most pump set, it use a better quality pump, and trigger set.
Mind you that I'm only a volunteer here. I'm one of the brothers that uses parts and pay in full prices, with a little discount that's being offer to all the brothers. I'm here merely as the voice of reason, with knowledge to share, and to guide the brothers to the better days. I don't promote, but simply indicate the products of choice with the full support of the brotherhood that is using them. I simply point out what is available, and best to be supported by the brothers. I've gone through too many pumps, but the pumps are mainly user error due to the lack of instruction and supports.
Also With all the equipment you can do the entire SRT routine
