Have used mine long enough to post a mini review.
In the end it approximates a Petri V2 in size, but differs with electroplated SS, MTL to DLH top air, a Velocity type deck that can do 1, 2 or 4 coil builds, has spit back guards and it doesn't leak. To me it's is a bargain at 69,00 €.
I personally like it better than the Petri V2 despite not being a fan of top air, but you can draw your own conclusions from it's specs...
GP Dripper Pro
A tiny beast for 4, 2 or 1 coil builds, with a very deep well. Overall height is only 23 mm!
Like his simple brother GP® Dripper, the Pro has the negative post and the deck made from one solid piece of EU certified 316 SS.
The GP® logo and the serial number are engraved at the bottom of the GP® Dripper along with the Heron® engine on the sleeve. The first production unit was sold on August 1 in retail price and delivered to American soil via DHL Express prior the regulation date of August 8 , so it is considered a grandfathered product.
All the materials for the construction of the GP® Dripper Pro are sourced from Europe and USA and it has the following specifications:
- The deck and the negative post are one solid piece of EU certified 316 SS and they have been electropolished afterwards for easy cleaning.
- The PEEK® thermoplastic rods for the insulators are made in Germany.
- Custom SS+ Ultem® drip tip with wide bore and spit back protection and Ultem® adapter with spit back protection for standard drip tips.
- The Ultem® rods in amber colour for the drip adapter and the drip tip are made in USA.
- The hex key for the posts is made in USA.
- The Viton® food safe o-rings are made in France.
- The packaging is made in Bulgaria.
- The precision machining was done in Greece and Bulgaria (facility A, facility B & facility C (VapourArt).
- It supports 4-2-1 coil function (2 AFC caps).
- Bottom feeder pin for squonker mods.
- Lung or MTL vaping (for MTL needs increased Wattage).
- 7 mm well and 11 mm from the top cap ensures great liquid capacity.
- Ability to accept exotic builds with multiple coils
- Excellent heat dissipation even with extreme Watts due to the top air flow.
- Small size with locking cap, solid construction with few parts.
- The air slots are designed to offer a silent operation.
- Custom CNC engraving.
- The top air slots ensure no leakage at all.
There is one AFC cap with 4 slots of 2 & 3 mm for 4 and 2 coil builds and another cap with 2 slots of 2 & 3 mm for single coil builds. The SS+Ultem® drip tip has spit back protection, the adapter too, 11 mm drip bore and it is held by one Viton® food grade o-ring designed in such way to hold the drip tip tightly. The air flow is achieved through the top air holes who are actually air channels 4-5 mm length, ensuring the proper air pressure towards the coils and additionally create an air curtain between the inner walls and the coils, anticipating the produced heat very quickly. For that reason increased wattage works better with this dripper even with low resistance values.

Note that they also have a GP Dipper model for 39,00 € that can be checked out on their website.
